>> i am evander holyfield. with all due respect to mitt romney, stay away. ♪ mark: on the show tonight, bill de blasio says he will not run first, benghazi. we learned that the house investigation might not be released until next year, maybe before election day.

that sounds bad for hillary for america. whatever the reason for the delay, this plays out over time is better for republicans. john: no, i don't necessarily think it is better politics for republicans. the clinton he would like this to happen sooner rather than later. we have a letter sent by david kendall, hillary's lawyer saying that she wants to testify in public, and have it happen soon. if there is anything they want to talk to her about, they should get this over with. they think it would be better for her to get it out of the way. if republicans drag this out there is a risk the party will start to think this is a silver bullet on hillary, and they thought benghazi was a silver

bullet. republicans could be led into the briar patch for this. mark: the closer he gets to election day, the more clinton folks can say this is politics. the clintons are overestimating the extent to which hillary clinton can do what she's done in the past, which is dominate republican questioners. the earlier it is, if it is done well, and they ask solid questions on the female issue, -- email issue, it could hurt her when her campaign is not off the ground. john: there is some chance, i agree with you that she will go out there and blow the room away and she will be stronger than any republicans on the committee. you can understand why they would like to get this over with. the last thing you want in a campaign is the unpredictable.

the proverbial surprise, you don't want the surprise lingering out there. they want to get this out of the way. i do think, i cannot overstate this, republicans who think that putting this off into election year, there is a risk on their side. mark: they should be pressing harder to do the right thing. some people -- and i do mean some people -- think bill de blasio should run for president. as wayne of "wayne's world" would say, excuse me? >> no. no. no. i'm going to say no again. i running for reelection of mayor of new york. i trying to talk about an issue

that i think is a profound national crisis that is going unaddressed in washington. i would do anything i can do but the issue of income equality front and center. mark: so he's not running. he isn't positioning himself. the question is, why hasn't the mayor of new york endorsed her yet? what is he waiting for? mark: he wants her to endorse it, but the de blasio agenda includes hillary from of them. there is furor in her camp that one the most prominent people has not endorsed her yet. it seems to me that he may be

playing a more dangerous game than he realizes. john: the only thing to get him to endorse her is the passage of time. every mayor of a big city thought that he was the sharp end of the spear of some progressive revival, he wants his time in the sun, this is the moment for him to get it. it's amazing that he is doing this to his old friend. there is no thing she can say that will satisfy him. the only thing to make him stop this is when of pressure comes on him from others in the democratic party. mark: she largely dances to the tune of the most liberal people in the party. an interesting question arises. will she do a -- in the context of the democratic fight? i get the sense she will not take it. john: it goes against her.

the sister moment happened when clinton was triangulating to play in the middle. she thinks the way to win is to mobilize and drive the obama coalition out to voters, and get young voters. that is what is driving a lot of her calculation about why she can't afford. mark: when a history of this campaign is written, the bill de blasio thing is going to be a not insignificant moment. let's read about the classic fairy tale of the brothers koch. david koch is looking favorably at scott walker. then charles koch says they are keen on a quintet of republican nominees. in chapter three, a koch memo that outlines a campaign plan

that also includes branching out with new chapters in red states. sounds very, very big. is too much being made of the koch's alleged possible and potential? john: no. two numbers -- 50 billion, and 50 billion. they both have net worths of $50 billion. they are super billionaires, who have played the political game very smartly. these guys are not just angels they could really move the needle, people are focused on it because they are really important. mark: in the immortal words of john mclachlan, wrong! they are testing whether outside

groups can turn out operations and data. the koch's network is divided. i don't think it will get behind one candidate. those five they are looking favorably on getting a ton of support from the koch network. there are a lot of huge players, and others will be significantly more decisive in the short term. john: wow. it's certainly true that it will dilute their influence. =mark: they are cautious. john: i grew with that, but the sophistication and the amount of money, you would be crazy not to pay a little attention to those guys. mark: you know i say? have a "koch" and a smile. john: clinton had a private fundraising session at somebody's home yesterday. what it is folks up to when they are not in public?

we never know what they are doing. what exactly do the presidential prospects and their advisers do? mark: we barely know. mike murphy, who is working with jeb bush, used to be a very visible guy. i have not seen him in public much. he is doing a lot of re-tweeting. sally bradshaw at a conference call which he announced that the major news she had to announce was that jeb bush had eaten pie. there is a lot of fundraising and strategizing. i have no idea. when these candidates are not in public, i can't quite figure out what they are doing, because they are low profile. john: mark, i know you are not underestimating the importance of pie.

you are not doing that. mark: it was big news. they were looking for something actually newsy. john: among senior staffing candidates, a lot of it is boring drudge work. they are hacking away, trying to raise money. there are obviously other moments that are important, but a lot of it really is just politics. what's interesting now is that with the rise of social media, and the fact that so many reporters now -- and there are so many reporters and donors -- they actually, as mundane as these things would normally be they make them even more monday and, because they are so afraid of what will happen to them. everybody is just being --

mark: on a future episode, we will have more on this. coming up, a showdown that is better than romney. can you believe that hillary clinton used to sell like this? hillary clinton: education education. i'm not sitting here like some little woman. mark: hillary clinton, coming up after this. ♪

mark: ding ding ding! in each quarter, barack obama and elizabeth warner. let's be joined by our guest

senator bob casey. a democrat from pennsylvania. thanks for joining us. bob: thank you. mark: as the deal moves to the senate floor, what are your chances of stopping them from getting to the president's desk? how you do it? senator casey: i think it is a very important debate to have. i wish we were given more time to be able to examine the deal itself. the first thing they have to confront is the trade promotion authority, which i think is a mistake.

for a variety of of reasons. when i look at this promotion authority as well as the trade agreement itself through the lens of pennsylvania and i see what has happened over the last 45 years, it seems that every time we have a deal like this, that both parties support, pennsylvania gets the short end of the stick. there is not the kind of job growth and expansion or janssen of the middle class that i would hope to get from a trade agreement. this is a difficult subject between and among them across but also for people in both parties. mark: you have been against a lot of trade deals since you have been in congress. you said your state has a lot of voters who support that. if you are from oregon or california, would you have the exact position you have intellectually and vote differently? or are you just representing your constituency? senator casey: i think it is a combination. i represent pennsylvania first and i have to fight to make sure we have strategies in place that

leads to the kind of wage growth that i think is the biggest economic challenge that we face. data shows that wagwes have grown barely at all over the last 40 years. i look at it from the data. setting aside the concerns of pennsylvanians and jobs, the data indicates, over time, we have not benefited certainly in the way that we were promised from nafta going forward. a lot of people disagree with me. we are having a good debate today. that is the first heart of the debate. john: someone who disagrees with you is president obama, who you helped elect. who cares a lot about wage growth and economic issues that you care about. he agrees or disagrees -- what is it that the president is not seeing that you are seeing? does he just not get it?

senator casey: look, there is a basic difference about the strategy to move the middle class forward when it comes to this issue. the president and i agree on increasing minimum wage. we agree on having the recovery act in place to kickstart the economy was good for the middle class. we agree on a lot of issues. on this one, and i heard him interviewed yesterday, the point he made was that he was rather critical as nafta he asserts -- i'm not prepared to review this assessment. his point of view seems to be that this is not nafta. the playing field leveling without getting undercut by low wages -- he would assert that all of those are better.

i just don't see it that way, and we have a basic difference of opinion. john: let me shift the politics. hillary clinton running for president. why have you not endorsed her? senator casey: i think it is early. you will be learning about that rather shortly. i think she is running a very good campaign. i think the issues she is addressing, especially the wage issue that she has been focused on that, whether it is wages or growing the middle class. i also think her approach in the campaign, talking to people in smaller settings and actually doing something that some of us candidates don't do enough of which is listen, it's a very effective way to talk to people, instead of just having the usual campaign metrics or activities. i think she is running a strong campaign.

i think she is going to be the nominee of our party, and i think she will be elected. mark: soon is now. you are about to endorse hillary clinton, aren't you? mark: i think you and john have been so effective, that i think we just have to wait a little longer. mark: you tell me if this person is qualified today to be president and chief? bernie sanders. senator casey: yes. mark: martin o'malley? senator casey: yes. mark: the former governor of rhode island? senator casey: sure. mark: how about joe biden? how are you going to look him in the eye and endorse and? senator casey: we don't know who is going to be running. we have one candidate for sure and that is hillary clinton.

mark: should we have a president from scranton? senator casey: i would love to have that, that would be wonderful. mark: so you're basically for biden, that is what you're saying. just kidding. if you are able to stop this from going through, what would the circumstances have to be to stop it? senator casey: we would have to marshall enough support and votes from the finance committee to stop the trade promotion authority. we will have amendments today, and it will have a vote at the end of that process. this is an uphill fight. anybody in my position to says otherwise is probably a little too optimistic. it is important to have this debate and it gives us a chance to talk about the middle class. mark: senator, thank you for coming to talk to us. senator casey: good to be with

mark: it's easy sometimes to lose track of where hillary clinton is from. york? washington? arkansas? our resident linguist explored the evolution of hillary clinton's accent. >> we are talking about accents. everybody has an accent, even if you don't think you do. some of us have more than one, like hillary clinton. hers have fluctuated a lot. hillary clinton: the road to being somebody in this society is education. >> that is hillary in 1983.

it is hard to tell whether she is pandering to the audience or mimicking the people around her. lots of politicians do the same thing. with hillary, you have three decades. let's go back to the 1983 clip. hillary clinton: start with education, education. >> she is from illinois, she married a guy from arkansas. that inland southern accent, it starts to fade four years later. hillary clinton: between personal privacy, family privacy. as a society, we have more than enough examples. >> there is a twang, but it is on its way out. the accent returns in 1992 when bill clinton runs for president. hillary clinton: i'm not sitting here, a woman standing by my man like tammy wynette. >> through the 90's, hillary discards the drawl.

hillary clinton: great, martha. >> side note, there are several appearances of martha stewart in the white house in the 90's, and they are all amazing. hillary clinton: questions come up and we will do our best to answer them. i think that is only natural. >> by the time she ran for senate, hillary clinton had to appeal to new yorkers. hillary clinton: when i started this campaign, i did not know what to expect. education. education. i hope you will give me that chance. hillary clinton: long-term. >> there is no strong accent here, but maybe the absence of an accent is in itself an accent. let's skip ahead to 2007.

hillary clinton: it's totally off base. it's hard to understand. what people are talking to me about is not that. >> we are almost pass the heartland into sarah palin territory. it does sound like she gets ever so slightly folksier when she is running a presidential campaign. obviously, she is not the first person to modify an accent for an audience. me and my mate were bloody knackered. ain't nothing wrong with that. mark: we will be right back. ♪
