questions there. mediabuzz@foxnews.com and i'll respond on twitter @howardkurtz. back here next sunday. hope you'll join us then for the latest buzz. donald trump gaining momentum in the race for indiana. trump pulling further ahead in the latest poll as ted cruz slips further away in his rear view mirror. hello, everyone. welcome to america's election headquarters. iarthel neyville. >> i'll gregg jarrett in for eric shawn. it's a crucial battle and could decide the republican nomination. trump and cruz going head to head in tuesday's primary with kasich sitting this one out. cruz now denying that had a loss would crush his efforts to keep trump from clinching the nomination. chief political correspondent carl cameron live in

indianapolis, and, carl, tell us about this new poll. >> reporter: well, it's suggesting that tuesday night could be decisive and in favor of donald trump. he has a 15-point lead over ted cruz here in indiana and that is a very, very big number, well, well outside any -- any sort of interpretation of the margins of error. in addition, john kasich works has dropped out of indiana, much the same way cruz will do so in new mexico and oregon as part of their attempt to sort of use their resources most successfully to block him from getting to the 1,237, so it's a blowout at this point, and yet the cruz campaign remains particularly enthusiastic and they had one little glitch here in indiana that actually took place just before the weekend when heidi cruz, the senator's wife, goldman sachs exec, suggested that her husband can unite the party because he's an immigrant and noted specifically a hispanic one.

that raises all kinds of questions because, of course, donald trump has questioned whether or not ted cruz is eligible for the presidency, and here's what trump said about all of this just a little earlier this moment. >> let me tell you, he's an immigrant. he's an immigrant from canada, because, you know, he lived in canada the first four years of his life. >> reporter: there's a chuckle in his voice, but that's heavy political artillery. may not be necessary if trump pulls off a big victory on tuesday night. >> well, carl, you mentioned that, you know, the cruz campaign is optimistic, sometimes, of course, in politics that's just for show. is there any way that cruz can catch up? >> well, it's difficult because indiana is a winner take all state, but it's one of these bifurcated deals. statewide, whoever wins gets 17 delegates. the remaining 23 of the 50 that are available here, 53 i guess, 27, pardon me, those are available through congressional districts, three delegates

apiece. there's nine of them, and as a consequence cruz can win there, and you can sort of do a road map of the communities and the places where he thinks his vote is going to be based on where he's been campaigning for the last several and will the next two, evansville, terre haute, south bend. these areas thinks there's a big conservative area to pick off congressional districts and he's been leading in the average of the polls by 6.5 points for weeks here. cruz has a tough haul and will be working his tail off the next few days. >> carl cameron live in indianapolis, carl, thanks for the rundown. appreciate it. >> reporter: you bet. a fox news alert. militants unleashed dual car bomb attacks in southern iraq killing at least 31 people and injuring dozens. this as the country faces a growing political crisis. the attacks also coming after the primes ordered authorities to arrest protesters who

attacked security forces after breaking into baghdad's heavily fortified green zone. kitty logan is live from london with the latest. kitty. >> yes, isis has claimed responsibility for these two bomb attacks which have killed at least 33 people. they targeted public areas in the southern city of someya. a statement hosted by isis says the intended target with members of iraqi security forces but many civilians, including children, appear to be caught up in these blasts. now, it is unusual for isis to attack the shia dominated areas in the south and its strongholds in the north and west of iraq but isis is not the only headache for the iraqi government right now. also today, hundreds of protesters are again camped out in baghdad's green zone voicing their anger about the delayed reforms. these are followers of shia click muqtada al sadr. it's the second day they have

reached this secure diplomatic area tearing down heavy concrete blocks. there are reports that it may be breaking up and one leader is urging people to leave but on saturday there were chaotic scenes as the same group stormed the government building, the parliament building also within the secure green zone. the iraqi prime minister has ordered authorities to arrest those who caused damage and also attacked members of parliament and police during the action. while the situation appears to have calmed since yesterday, it is by no means resolved, and there is overall concern about this political chaos, a fear that the iraqi government is losing its grip at a time when the u.s. wants it to focus on the fight against isis and it's counting on that saturday. arthel. >> emotions continue to run high there. kitty logan, thank you for the latest there from london. gregg. >> >> the growing turmoil in iraq could have major implications for the u.s. strategy in fighting isis in the region.

that's because the white house leans on the iraqi prime minister al abadi in battling the terror group and his political viability could be a huge factor in whether our plans could succeed or fail. joining us to talk about it is ambassador john bolton and senior at the american enterprise institute and ambassador, it's good to see you. stated goal of the protesters is to bring down the government of the prime minister and that's a government, as we say, the united states supports. vice president biden was just there. where do you think this is heading? >> well, this is a clash among shia iraqis, the muqtada al sadr who leads essentially a populist group of militias against al abadi under the control of the

ayatollahs in tehran so the impact of this really calls into question whether what steps iran will have to take to reassert control. middle eastern news sources today are reporting that other shia militia more supportive of iran are moving into the baghdad region, so we could see more activity later this week. >> yeah. >> as far as what we're doing against isis and how the turmoil in iraq affects that, honestly i wouldn't be doing anything with the existing government in baghdad anyway. it simply strengthens iran's hands in what used to be iraq, but that's the obama administration policy, and that policy, one would have to say, is under duress as long as muqtada al sadr's followers are running through the has of parliament. >> yeah. looks like they are not going to stop any time soon. a few months ago in november you penned a column, and i re-read it this morning. you argue that the best alternative to isis in northeastern syria and western iraq is a new independent sunni

state. do you still believe that, and how would that help the crisis going on there now? >> well, i think you need to provide some incentive to sunni arabs both in iraq and syria, territory that isis controls to fight against isis, to help destroy it. i don't think the sunnis in iraq are going attack isis so they can come back under the control of the government in baghdad controlled from tehran and likely sunnis in syria are not going to fight isis so they can come back under the rule of bashar assad. i think what you're seeing in baghdad now is one of the consequences of what i believe is already the break-up of the country we used to know as iraq. i think the kurds are well out of it. the sunnis aren't going to listen to the government in baghdad as long as the shia control it, and what the protests these past couple of days demonstrate is conflict among shia groups for control of what's left of the state, so i

think this is just more evidence of continuing descent into anarchy across the middle east as a whole. >> what happened if al abadi doesn't survive there? >> my guess is whether al abadi himself remains the leader or somebody else is brought in, iran is not going to tolerate its position being weakened, and it wouldn't surprise me if by the end of the week either there are clashes between these competing shia militia, the badr militias apparently are moving towards baghdad or as is the custom in the region, the iranians and muqtada al sadr cut a deal and emerge both happy. >> yeah. what a sunni state, as you sort of laid it out in your column, also stand as a bulwark against a shiite government in baghdad that is, as you appropriately point out, deeply influenced, if not controlled by iran? >> right, and when i say a sunni state, what i mean is a new

state composed largely of sunni muslims, not that i want a theocracy. >> right. >> but i think the real threat in the region, once we defeat isis, which i think we could do if we got our act together along with allies in the region, the real threat remains iran, still the largest state sponsor of terrorism, still pursuing deliverable nuclear weapons, still trying to get hegemony on the ground through the baghdad government and assad regime what's left in syria and among hezbollah and others. that's the real threat to peace and security in the region. that's where we've got to keep our eye on the ball. >> what does the current turmoil in iraq do to the plans to try to retake mosul, which, of course, is iraq's second largest city and controlled still by isis? >> well, i think that's where the most immediate effect could be felt. obviously if elements of the particularly shia population in iraq are fighting each other,

it's very hard to see how the iraqi military can get itself organized to move forward. i think mothers will tin to take advantage of this. if iran doesn't move quickly to restore order of the sort it wants in iraq, then things could get worse all around. you could see the kurds moving to take other territory and the government continue to fragment. as i say, i think iraq is gone, whether we like it hornt h.this is just more evidence of it. >> indeed. ambassador john bolton, thank you, sir. good to see you >> thank you gregg. >> will a portion of the brussels airport damaged in the deadly terrorist attacks in march partially reopened to passengers today. the newly repaired departure hall opening after a special ceremony. extra security checks are now added before people can enter the terminal. prior to today passengers had to use a temporary check-in tent due to the extensive damage. 16 people were killed in the terminal in two suicide

bombings. another 16 people were killed in a subway bombing. and here at home, tomorrow marks five years since the death of osama bin laden, the mastermind of the worst terrorist attacks ever on american soil. bin laden was killed in pakistan in a daring raid by u.s. navy s.e.a.l.s nearly ten years after nis. cheering crowds gather fled d.c. and new york city to celebrate the news. more live from our d.c. bureau with more on this story. garrett? >> reporter: arthel, one of those moments in history where almost anyone can remember where they were or what they were doing when they heard we got him. tomorrow on the fifth anniversary of the raid that killed lad latd there are no events scheduled by the administration to commemorate that event here in d.c., but we are hearing new details from the president about what night and what went into his decision to green light the mission which he says was their best chance to get osama bin laden, and if they didn't, it could have been years before they were able to find him glen.

>> if it wasn't bin laden, probably the costs would outweigh the benefits, and, you know, we would lose face internationally because there was probably going to be a lot of difficulty keeping it secret once the operation started. and the navy s.e.a.l. who fired that fatal shot described that very moment in a fox news special in 2014. >> standing on two feet in front of me was the face that i had seen thousands of times, ubl. very quickly did i recognize him and then just pop, pop, pop. >> this morning on "fox & friends" rob o'neill says he didn't do it alone and hopes others will come out and share their stories of that mission as well. >> i'm a face of the team that did it, and just to closure, when more of the guys come out and tell their stories because there's going to be 23 different stories to that mission. >> five years after bin laden's death this anniversary leads to increased terror warnings around

the globe, a sign and indication that this fight against terror still rages on. arthel. >> indeed. garrett tenney, thank you very much, garrett. a freight train jumps the tracks in the nation's capitol and spilling out potentially hazardous liquid. how it's affecting the area, and california's primary shaping up as a very meaningful one for the first time in decades. donald trump says the race is over, but can the golden state prove otherwise? >> yes, it's over. i think it's over now, but it's over. cruz cannot win. he's got no highway. got nothing. he's way behind. i'm leading him by millions and millions of votes and by 400 or 500 delegates. he can't win. baas uh oh. what's up? ♪ ♪

on a long-term asthma control medicine, like an inhaled corticosteroid. breo won't replace a rescue inhaler for sudden breathing problems. breo opens up airways to help improve breathing for a full 24 hours. breo contains a type of medicine that increases the risk of death from asthma problems and may increase the risk of hospitalization in children and adolescents. breo is not for people whose asthma is well controlled on a long-term asthma control medicine, like an inhaled corticosteroid. once your asthma is well controlled, your doctor will decide if you can stop breo and prescribe a different asthma control medicine, like an inhaled corticosteroid. do not take breo more than prescribed. see your doctor if your asthma does not improve or gets worse. ask your doctor if 24-hour breo could be a missing piece for you. see if you're eligible for 12 months free at mybreo.com.

crews in washington, d.c. working to clean up after a freight train suddenly jumped the tracks. that train carrying potentially hazardous liquid that's now spilling out on to the streets. d.c.'s metro transit system suspending service in and around that reaction and they are running shuttle buses instead. no injuries have been reported. >> what did reagan do? he cut taxes. he lifted regulations. we saw millions and millions of

new high-paying jobs that generated trillions in new government revenue, and he used that revenue to rebuild our military, to bankrupt the soviet union and to win the cold war. >> consider him a conservative. folks, i'm a conservative, but at this point who cares. we've got to straighten out the country. i mean, give me a break. >> well, the republican presidential contest putting california in play for the first time in decades, and it comes at a time when the state's republican primary is undergoing a major political shift. john fund is here. he's a columnist for "national review" so, john, first of all, hello, and -- >> thank you. >> let me get your assessment. is there a major shift in the republican party in california, an before you answer, tell me this as well. does donald trump have a point that it's not about conservatism but currency as in better paying jobs? >> oh, i think a lot of general election voters will think that. the problem is trump doesn't do

well with general election voters, and the problem is before trump gets to the general election he has to win the hearts and minds of consistent california primary voters who are consistently conservative, so when he goes out in front of them and says, look, i'm a conservative but who cares, that's not exactly an inspiring message. >> what about that shift in the republican party there in california? >> well, donald trump has a lead probably if you average out all the polls in california, but i think it's a shaky lead. it depends on how well he does in the races leading up to it, whether or not there's a sense of inevitability about his winning the nomination. cruz pulled a surprise at the convention. pete wilson who is both a moderate on social issues when he was governor and was also very hardline on immigration came out very enthusiastically for cruz and said donald trump was a wild card who couldn't be trusted with the nomination. >> is that going to boost voters to the polls for ted cruz though? >> well, i think it gives credibility to cruz who is often

viewed as a hardline conservative and here we have had a moderate california governor, the last republican governor in california, coming out and warning against donald trump an endorsing ted cruz's credentials. it makes some difference. again, trump is probably in the lead and cruz has a lot of catching up to do. >> as we know, you know, california has the largest hispanic population in the country, so will the immigration issue put up a wall and block trump from winning the california primary? >> well, i think it helps him in the california primary. duncan hunter whose district is along the border in san diego. >> right. >> has a lot of trump supporters in his district. i spoke with the state senator from san diego who says trump is wildly popular there, but a lot of californians don't view immigration as their top issue because since the great recession a lot of mexican-americans have gone home. a lot of illegal immigrants have gone home because there aren't any jobs in the u.s. i think trump is going to have to sell himself as more

presidential than he has been so far, and, frankly, that speech in california didn't do it for him. >> so then, john, if you're saying that immigration is not the big issue in california anymore, then what is the issue, and which candidate stands, you know, the better chance to -- to drive that point home? >> well, trump has campaigned against washington, d.c., and cruz has campaigned against washington, d.c. people are mad at the federal government. they feel that they have been lied to. they feel that they haven't gotten the pay raise in 16 years if you look at the stagnating incomes. they are upset. a lot of them still believe that you need a complete outsider like donald trump to shake up the system, and a lot of trump ice attacks on cruz as being untrustworthy have worked, but, again, trump's problem is he doesn't win in november if you look at any of the polls. cruz is competitive. so it depends on what california voters think is important. do they want a winner in november or a full-throated populist who speaks their plain language? >> before we go, let's quickly

turn over to the democratic side of this race, still talking about california. hollywood has a long standing affection for the clintons. however, as you know, a lot of stars are stumping for sanders, so how do you think the primary out there is going to unfold for the democratic candidates? >> well, people in hollywood, and i used to work there, believe did or not, people in hollywood want a winner and hillary looks like a winner. the problem is she's also been around for 25 years, and she's taken a lot of money out of hollywood. she's burned some bridges. david geffen, the media mogul, you know, said a few years ago said that the clintons lie with great ease and rapidity, and he's not backing anyone this year, so i think there's clinton fatigue in hollywood, even though the majority of stars are on board with hillary. there's very little enthusiasm, unlike previous years. >> do you think she will win the primary out there, or do you think trump will, yes or no? >> sanders versus hillary clinton, i think hillary has a narrow lead, but if the turnout is low enough and california democrats, you know, haven't

seen a lot of commercials, haven't seen a lot of commitment about the race, it's possible that a low turnout that sanders could pull an upset and beat hillary narrowly but she would still have an enormous advantage in delegates nationwide. >> got to leave it there. i'll let you slide on not answering about the trump thing. >> john fund, god to see you. >> i'm sorry, i thought you meant clinton versus sanders. >> i said trump, too, on the gop side. >> i think clinton would beat trump in california in november, sure thing, no problems. >> okay. >> thanks, john. >> pretty democratic state these days. all right. speaking of democrats, the big "d," that's president barack obama, got a last chance to roast his colleagues, politicians, movie and tv stars gathering at the white house correspondents' dinner last night. you know, it's affectionately called the nerd prom. seems a little unfair. it was president obama's eighth appearance at the event and his last as..

>> it is an honor to be here at my last and perhaps the last white house correspondents' dinner. i know i was a little late tonight. i was running on cpt which stands for jokes that white people should not make. this material works well, i'm gonna use it at goldman sachs next year, earn me some serious tubmans. >> comedy central host larry wilmore was the featured guest and took the podium after the president and that's a tough thing to do, and, you know, a lot of people on social media are saying he was more -- wilmore, that is, was more mean than funny or humorous and so forth and dropping the "n" word was a little unfortunate but that's my opinion. >> and i have two seconds so i'm not going to say anything. i can't address that in two seconds so i move on >> you can't. >> it is a condition that impacts millions of people.

coming up, we're going to talk about some of the biggest warning signs of stroke and what you can do about it. baas we asked a group of young people when they thought they should start saving for retirement. then we asked some older people when they actually did start saving. this gap between when we should start saving and when we actually do is one of the reasons why too many of us aren't prepared for retirement. just start as early as you can. it's going to pay off in the future. if we all start saving a little more today, we'll all be better prepared tomorrow. prudential. bring your challenges.
