(BEGIN VIDEO CLIP)

BRET BAIER, ANCHOR: I'm wondering, with the backdrop of the e-mail investigation with the FBI, if now you regret saying at the beginning that you didn't give a damn about...

SEN. BERNIE SANDERS, DEMOCRATIC PRESIDENTIAL CANDIDATE: No.

BAIER: ... Hillary Clinton's e-mails.

SANDERS: No. Absolutely no regrets at all. In fact, I would argue that the reason we are doing well is that people understand we are trying to run a different kind of campaign, not one of personal attacks.

Well, I think this is a very serious issue. I think there is a legal process right now taking place.

HILLARY CLINTON, DEMOCRATIC PRESIDENTIAL CANDIDATE: Let's see what it is, and let the American people draw their own conclusions. This is very much like Benghazi, George. You know, Republicans are going to continue to use it, beat up on me. I understand that. That's the way they are.

(END VIDEO CLIP)

BAIER: Well, that's the e-mail issue, Bernie Sanders kind of sounding different on that today, and Hillary Clinton defending.

Take a look at that Des Moines Register/Bloomberg poll on the Democratic side, Clinton at 45 percent, Sanders at 42 percent. And inside this poll, Clinton gets 65 percent of the caucus goers 65 and older, Sanders only 27 percent. High income prefers Clinton. And among those under 35, 63 percent give U.S. Senator Bernie Sanders their support, 27 to Clinton. First-time caucus goers for Sanders, 53 to 34 -- some of the internals there.

I'm back with the panel. Steve, what about this transformation of Sanders?

STEVE HAYES, THE WEEKLY STANDARD: Yes.

BAIER: You've been talking about this.

HAYES: Sort of abrupt, right? I mean, you asked him if he had any regrets. He said he had no regrets at all. And then two days later, he's saying, in effect, I have regrets, this is a serious issue.

You know, the interesting thing about the discussion of the e-mails with respect to the Democratic campaign is Bernie Sanders characterizes it as a personal attack. It's not a personal attack. This is a serious investigation being conducted by the FBI. For him to say, just to acknowledge the existence of the investigation and to say this raises questions about her conduct in office is not at all a personal attack.

I've been a little surprised that he continues to be reluctant, but maybe we're finally seeing that cracking.

BAIER: Brit?

BRIT HUME, FOX SENIOR POLITICAL ANALYST: Steve is entirely right. I mean, it's not like Steve's saying that, you know -- I mean, it doesn't -- just because you're not criticizing somebody for their position on the HUD bill or something doesn't -- doesn't mean you're mounting a personal attack.

And you know, I look at -- I look at this, and I think it's amazing that she can weather this to the extent that she has. But there's a very interesting number in this Iowa poll. When people were asked about whether this United States economic system is rigged against the little guy and that the fix is in, you know, the Republicans think, by and large -- half of them think the system is basically fair. Sixty-seven percent of Iowa Democrats responding to this poll said they think the whole thing is rigged.

And of course, that's Bernie's sweet spot.

BAIER: Yes, wheelhouse.

HUME: Yes, well, I mean, basically, his campaign is based on a conspiracy theory that the Wall Street overlords are running all our lives. I mean, it's far-fetched, but widely believed.

BAIER: A.B.

A.B. STODDARD, THE HILL: Well, the numbers in there with her and young people, including the numbers Brit referred to, are really terrible for her come the general election, should she be the nominee.

But this is a big day for her. She went on ABC News today and was asked about the e-mail thing and said two things that are untrue. One, it's an interagency dispute.

(LAUGHTER)

STODDARD: And two, that you have classified material always needs a marking. Both of those things are not true. This is a very serious problem for her. It might not be in Iowa, might not be in New Hampshire, but it might be later.

BAIER: This non-disclosure agreement back in 2009 that she signed, that classified information is marked or unmarked, including oral communications -- I mean, it seems cut-and-dried, Charles.

CHARLES HURT, WASHINGTON EXAMINER: And if Democrats are smart, they are going to want to have this debate as fast as possible because once you -- you know, once you get past the primary, there's not going to be any sort of doing it over.

HUME: Information is not classified because it's marked. It's marked because it's classified.

BAIER: Exactly.

HUME: And she has used that marked versus unmarked business to try to slide past this forever, and I think those days are over.

(CROSSTALK)

HAYES: ... on the mainstream media...

(CROSSTALK)

BAIER: We can call her on it, if you want to, in the Democratic "Candidate Casino" by depending on where you want to put your hundred dollars. Very quickly, a lightning "Casino" on the Democratic side. Steve, go ahead.

HAYES: I'm calling her on it. I've got her at $60, Sanders at $20 and $20 on Joe Biden in the field because I think this is a serious matter and it could result in an indictment.

BAIER: A.B.

STODDARD: I'm giving $20 to Biden, Warren or somebody else. But I'm still putting $75 on Clinton because I believe that the machine of the party is powerful enough to stop Bernie Sanders, who's received more contributions than any political candidate in the history of this country, and I think he has $5 chance of winning the nomination.

BAIER: Charlie?

HURT: $30 each to Clinton, Sanders and Biden. And the only reason I give $10 to O'Malley is because I had $10.

(LAUGHTER)

BAIER: Although he could be key in the caucuses.

(CROSSTALK)

HURT: It'd be on beer or liquor maybe.

BAIER: Because in the caucuses, he might not get to 15 percent, Brit, and he could go to Bernie Sanders.

HUME: Anything can happen. But I give Bernie a little more chance than my colleagues because I think if he wins here, or nearly wins here, and then wins New Hampshire, that all of this stuff about a southern firewall may go out the window because news travels fast and big, and people take a fresh look, and he could give her a run for her money all the way.

I've got Biden in there, as you noticed. But that would be Biden/other because -- I don't know, if she gets indicted, all bets are off, and you don't know who could get in.

BAIER: Well, the "Casino" thanks you for your bets. Panel, thank you.
