is now under scrutiny. why they say he's sharing too much. but we begin with the u.s. mid-term elections. fewer than half of the registered voters are expected to turn out. >> they say they don't see their votes making difference or they're fed up. here's at stake. 435 seats in the house and 36 of the 100 seats in the senate. joe biden spoke with gloria borger. >> i don't agree with the odds make makers. i think we're going to keep the senate. >> reporter: what if that would be the case? >> i don't think that will

change anything about what we're about. we know what we have to get done the last two years, and quite frankly, going into 2016, the republicans have to make a decision whether they're in control or not in control. are they going to allow things to happen and continue to be obstructionists? and i think they're going to choose to get things done. >> all right, joe biden there. let's get a live look at the races to watch. thanks for talking with us. we heard the vice president joe biden and some other democrats insist they can hold onto the senate. but the numbers don't look too good, do they? >> no, they don't. it's really shaping up to look like a bad night for democrats. at the same time, a lot of the polling out there is really not being trusted by some of the

tra strategists, because as you mentioned earlier, it's hard to predict what the universe of voters is going to be in the mid-term elections. and i was just in the two big states to watch tomorrow night, iowa and colorado and talked to so many voters who have absolutely no interest in showing up tomorrow. don't feel that their votes are going to make a difference and really aren't happy with the direction of the country right now. >> i'm interested in looking at what the new polls are telling us about the critical seats to watch. you mentioned a couple there, but also, too, what plays into this is turnout, because in the end, it doesn't matter what the polls say if people don't turn out to of what. but let's look at those states that need to be watched. >> yeah, the states that obviously the republicans need to flip six states to take control of the senate. and right now three of them are looking pretty good for them.

in south dakota and montana and west virginia, but really, the ones to watch tomorrow night, especially on the early side are going to be new hampshire, north carolina, then you're going to be looking at iowa, colorado, and arkansas. i mean, a lot of these states are looking really, like they're going to be tough for the democrats. president obama has been a huge drag on democrats this year. he has not campaigned at all in the south for example. and so we'll start to get the picture kind of early on in the evening about how things are going. but it really is going to depend on turnout, and whether the republicans have been able to gin up their turnout machine the way that they said they've been able to do this year. >> you mentioned mr. obama. there's some describing him as an albatross around their necks, which is interesting. if the republicans do take control of the senate, and that seems to be the overwhelming

view, what's that going to mean for this country? >> well, i think that there's two schools of thought on that. one is is that we could see a lot more gridlock. but on the other side of it, if republicans are in control, then maybe there will be more of an impetus for them to compromise with the president. and, you know, you have to look ahead to the presidential race in 2016 as well, where they are going to have to make inroads with latinos, for example. they probably will have some motivation to do some work on immigration for example. and, you know, so we'll see. maybe they'll feel like it's better for them to tart making some deals with the president, which certainly would be a change from the tenor of the last couple years. >> the democrats would be happy with that, wouldn't they? thank you for talking with us. appreciate it. throughout the mid-term campaign, republicans have focused their message on a

president with record-low approval ratings, blaming him for pretty much everything and many democrats have distanced themselves from mr. obama, even on issues which would normally play to the president's strength. here's joe johns. >> reporter: with their biggest weapon in president obama mostly sidelined, some democrats went for the hard strings in a desperate bid to get blacks in the south to go to the polls, invoking the shooting death of trayvon martin in florida as a reason to vote in north carolina. a radio ad generated by harry reid's super pac, dedicated to maintaining democratic control of the senate. putting race at the center of the senate race. >> led the effort to pass the stand your ground laws that caused the shooting death of trayvon martin. >> reporter: republicans responded with a tough radio ad

of their open, calling out the democrats. >> you heard this kay hagan ad paid for by harry reid's super pac. >> reporter: and images from ferguson, missouri where another young black man, michael brown, was shot to death by a police officer. >> race is a very real issue for us as black people. but i think it's disappointing when you have democrats that number one, just take the issue of race and use it to incite without any factor basis. >> reporter: democrats deny this is about inciting local anger. they want them to think more about the judges, prosecutors and others who allocate justice. though the tactics are not embraced by all african-american politicians. but atlanta's city councilman says it's valid to talk about in the mid-terms. >> i would not use these in a

campaign if it were my personal campaign, but i would want to make sure that we have dialog and that we bring all parties to the table. >> reporter: still, dialog over race is trick eye. louisiana's mary landrieu got tough criticism after she said this in an interview with the nbc about the south and the president. >> the south has not always been the friendliest place for african-americans. it's been a difficult time for the president to present himself in a positive light as a leader. >> reporter: the question is whether it could backfire, polls show black voters overwhelmingly support the president, while turning off-white voters. >> generally these appeals are targeted. they are fliers or mail in predominantly african-american neighborhoods or radio ads on predominantly african-american radio. and so it's this sort of slicing and dicing the electorate.

>> reporter: tough choices for democrats, and only hours before we know whether they pulled the right strings to get one of their most critical voting blocks to the polls in a tough election cycle. cnn, lexington, kentucky. and please, tune in on tuesday night for complete coverage of the u.s. mid term elections, election night begins 5:00 eastern time for viewers right here in the united states. if you are overseas, a quarter of midnight in london is when all the action begins for our international viewers. a british investment banker is charged with two murders in hong kong and will be back in court next week. and now we learning new details about him. >> he had little to say in his first court appearance on monday. but james blake reports one of jutting's friends is speaking.

>> reporter: the british banker said almost nothing inside. he was asked if he understood the charges against him and replied simply, i do. the body of a woman was discovered in his luxury apartment in hong kong, packed in a suitcase and left on the balcony. he's also suspected of murdering a second woman in the early hours of saturday morning. the 29 year old earned a six-figure salary at the bank of america merrill lynch. >> he was a nice guy. he was very nice to the girls. he told me he had financial

tells cnn u.s. military is pressing for major offenses in the coming weeks and months with at least critical targets, retaking the city of mosul, bringing the oil refinery back under full iraqi control and winning back al anbar province which the u.s. has vowed to keep safe. but even a modest effort will require thousands of iraqi troops, trained, equipped and motivated to fight, something that has not yet fully happened. >> barbara starr also reports the concern over the lone wolf scenario is so great that the u.s. is increasing security screening of travelers coming to the u.s. from europe and from other allied countries who may not need a visa to enter this country. well, it has been more than a month now since 43 college

about his venture. >> reporter: virgin founder richard branson tells me he will not speculate about what caused this crash. he did say they are moving forward, that indeed they still want to bring civilians to space and that he will be the first to go. but given this tragedy and the death of a pilot, i asked him, is the risk still worth it? >> yes, the risk is worth it, and mike would have been the first to say that. i'm sure his parents and wife and sisters would not say that. but test pilots would say that, because they know the risk they're taking. they know the importance of what they're doing. we've got to go through the difficult testing stage of creating a space line in order to make it safe for traveler whose want to travel on that space line in the years ahead. and, you know, we will succeed.

>> reporter: cnn aviation analyst miles o'brien has said that you and virgin galactic have underestimated the risk involved. he said really there is a gloss painted on this that does not reflect reality. what is your response to that? >> there have been some incredible things said over the last few days since the accident. when you have an accident you are going to get people quick to criticize. what is a pioneering program. and we have 400 of the best engineers in the world working on this. they are diligent, hard-working, doing something which is cutting edge. and i support them 100%. so, you know, we're, we have to accept the occasional knock. but we'll brush it down and move forward. >> reporter: now i also asked

branson if they will send more test pilots into space before the final investigation is complete. he said the ntsb has told them to move forward as they were. they are nearly complete with building another spaceship. so they may be sending more test pilots up before the final investigation is done. i can also tell you that i asked him about the new fuel mix being used in this rocket on friday for the first time. he denied that that had anything to do with the crash. we still, though, have to wait for a final word, of course, from the authorities. poppy harlow, cnn, new york. and within the last hour, the ntsb held a news conference on their investigation into the cause of the crash and have confirmed that it was the co-pilot who unlocked what's known as the feather control system. that is used to control the descent of the ship. and it appears that was

activated prematurely. they're not saying that's what caused the crash. but they're saying that's what happened. they're still saying it could be a year or so before they could know. >> and richard branson said don't jump to conclusions, but this seems to be, so pilot error, perhaps. >> still a long way to go. the planet's strongest storm is still churning towards japan. let's go to pedram for more on this. >> i will start you off here across the western pacific. because this particular storm getting up to well in excess of what would be a category five, even a strong category five, has now weakened to 150 per mile winds, which is a threshold to what would be considered a super typhoon. and this is nori. you take a look at the numbers

here, actually quite quiet here when it comes for storms to date. we've had 19. 11 typhoons. but notice these super typhoons well above the average of four to date. and we've seen seven so far with nori in place. these islands scattered about tokyo, these are the izu islands. i think it will impact some of the islands just offshore. and notice significant weakening as it approaches thursday and friday. but travel so far the next couple of days. this is the scene right now. some fog across the board in tokyo's main airports, haneta and it is across portions of mexico we're watching carefully. that is hurricane vance sitting

out thayer, a very strong category two, about 175 kph. this storm closing in on category three, but notice how small the size is. it's the 20th storm of the season, a v-letter stormed. the last time we had this many was in 1992. so pretty active in this portion of the world. it will weaken rapidly as it approaches the western coast of mexico, it's going to be impacted sometime thursday night into friday. generally 100 to 150 millimeters of rainfall left in the forecast. but we take you to australia. look at these teens out there. we are three weeks away from the summer season. absolute beach day. you take a look at friday, the 31st of october. temperatures all topping out at 30 celsius, 86 fahrenheit, first time since 1979 all those places

moved in monday. the elections are being touted as a referendum on president obama. >> they are a few seats shy of taking control away from the democrats. we take a close look at what's at stake. >> reporter: $4 billion spent, 2 million television spots aired and 17 million early votes already cast, this has been a long election. but after all that, the only number that does matter in the end is six. that's the number of seats the republicans need to win back the senate. the outlook for republicans is rosie. >> i'm asking for your votes. >> reporter: the math in a favorable environment are on the gop's side, giving them a real shot at the big prize this year, control of the senate. to win a 51-seat majority, republicans only need to pick up six seats, and they have many

different paths to get there. count montana, south dakota and west virginia as gop shoe ins. to pick up the rest they only have to win three among these toss-up states where their chances are good. >> we will make history. >> reporter: but democrats aren't waving the white flag yet. and for good reason. the polls in all these battleground states are extremely close. many dead even. and democrats are hoping to flip a couple seats themselves in kentucky and georgia. >> take me across the finish line. >> reporter: in the house of representative, it's not a question if republicans will keep their majority, but by how much. they're aiming for a double-digit jump to 245 seats. >> power belongs to the people. and that's what we're going to do. >> reporter: as for the issues motivating voters, the economy is still the top concern, despite the threat of isis and ebola flipping the script in many races so close to election day.

in washington, cnn. it turns out there are some wildcards in play during this election. independents who might just sway the outcome of the mid terms. >> our jim sciutto has that part of the story. >> reporter: william jefferson clinton. tomorrow's election may seem all about democrats and republicans. but control of the senate may come down to an independent and two libertarians. here in kansas, millionaire greg orman is an independent running neck and neck with pat roberts, a gop veteran. no democrat is competing here -- orman has recoiled at saying which party he'll caucus with. >> washington's broken. we all know it. i believe we can have another american century, if we elect problem solvers, not extreme

partisans. >> reporter: orman may sound a lot like this woman in georgia. >> republicans and democrats have failed us with the same old broken promises for decades. >> reporter: democrat michelle nunn, daughter of former senator sam nunn and david perdue. and amanda swofford shaking up this race. it could require a runoff. a runoff means this race and a question of senate control may not be settled until january. then there's north carolina, another race too close to call. libertarian shawn haw is a pizza delivery man who's made a name for himself with folksy ads recorded in his friend's basement. >> we need to stop all war. and stop spending more money

than we have. >> reporter: his stand on legalizing marijuana has lit up the race. get haugh, get high. the question, does he steal more from republican thom tillis or democrat incumbent, kay hagan. >> and jim joins us now from kansas city. if you look at the rise of those inld pent candidates, that seems to indicate that this won't be a wave election for the opposition party. so why aren't republicans doing better? they'll peck up some seats, probably get the senate, but shouldn't they be doing better than this? >> reporter: the fact is they're doing pretty well. chances are more likely than not that they will take the senate, but you do have other forces in play here, one being a general frustration with washington, anger at dysfunction in

washington. one of them in kansas, an independent running neck in neck with a 30-year veteran, pat roberts who typically in this election, with obama having low approval ratings might be in a better place, but that outside appeal havable an effect. more potential. but broadly, you have that major frustration. the major candidates have a major advantage. but in terms of the republican pickup, it's looking like probably around six seats, and that's fatherly typical for a second-term president in his mid-term. so they'll come away with something, chances are it looks like a decent win, by why not much more? it may be a lack of general enthusiasm about what's going on in washington. because neither party, for voters, don't find either party particularly appealing.

>> republicans pick up six seats, which means the democrats can still fill buster. the president still has the power of veto. so will the next two years look a lot like the past six years? >> reporter: you almost have to cyan say there's a pretty good chance of that. there is a counter opinion in washington that having this divided government might actually be an advantage, even for the president. that there'll be incentive, then, to work together. and you hear this from the white house, you hear the white house working on a legislative agenda that they can work with a republican-controlled congress if there is overlap on trade agreements giving the president more freedom to sign trade agreements. also possibly on a corporate tax deal, that there is some overlap. and from the republican side there is incentive to make legislative deals because they will no longer be the party of opposition. they will be in charge of the hill.

and you've got a big presidential election coming up in two years, the thinking being if republicans do nothing purely stone wall during that time period, it will hurt the chances of the republican candidate in 2016. trouble is, john, we've heard those kinds of arguments every two years here, and sadly, you often find that the two parties find a way not to agree on anything, so i think there's a decent chance of that. >> jim, always great speaking with you. thanks so much. >> reporter: thank you. cnn's election night in america coverage begins at 5:00 eastern for viewers here in the unit. join wolf blitzer, anderson cooper and cnn's entire political team for results and analysis. and for our international viewers, coverage begins at quarter to midnight tuesday in london. >> everyone will be staying up late to watch. >> they will. to watch the outcome. >> and full coverage right here on cnn. in the meantime, we'll move on. what really happened with in

intended to do. these are my brothers i've served with. >> reporter: his lawyers say they're not aware that any sensitive information was released in his speeches and no criminal charges have been filed. the former seal doesn't mind being held accountable but wonders why leon panetta seisn' getting that kind of scrutiny. we've asked leon panetta for comment. we've not gotten it. the government had already been trying to seize profits from bissonette's book. >> we don't advertise the nature of our work. being a navy seal, serving our country is great. but people want to know what we do and how we do it, but so does our enemy. >> reporter: he tried to contact his former commander to explain

why he wrote the book on the bin laden raid. he says he respond toed ba him g "delete me." there were the details given to the makers of zero dark thirty. want to turn to the story on ebola and we've talked about kaci hickox who has reached a deal that allows her to freely travel while monitoring her health. >> the nurse who recently returned from sierra leone says that despite the agreement she plans to mostly stay at home anyway. >> i completely understand that this town has been through a lot, and there's still a lot of fears and misinformation out there. i think we need to start addressing those issues, but

it's also true that i only moved here to maine in august. so there are a lot of people who don't know me. i'm still an outsider, and i just sort of want to respect their wishes, but i really hope that one day in the near future i can come back from an ebola assignment and walk into the grocery store and people would smile and say hi. >> i'm fairly certain they know you now. and local authorities had wanted her to stay in voluntary quarantine at home for a full three weeks after returning from africa, even though she has continued to test negative for ebola. >> yeah, and as she has pointed out, despite the science, it's very hard to tackle the fear, at least here in the united states and beyond. it's right across the globe. >> it's been very widespread, it seems to be calming back down, getting to a normal level of paranoia. let's take a break now. it was a site known the world
