    NEIL CAVUTO, HOST: To the man who wowed them at this convention last night — and he's not even a Republican — Joe Lieberman, who no doubt will be considering food-tasters when he returns to the Senate.

    (LAUGHTER)

    CAVUTO: Senator, very good to have you.

    SEN. JOSEPH LIEBERMAN (I), CONNECTICUT: Great to be here.

    Are you available for the food tasting?

    (LAUGHTER)

    CAVUTO: Man, oh, man, I was thinking after watching — I think, A, do I have this right?

    LIEBERMAN Yes.

    CAVUTO: And, B, did I hear Republicans in the audience cheer for Bill Clinton?

    LIEBERMAN Well, it was quite a night.

    I must say that I — of course, I thought about it. And I — one of my — one of the reasons I'm for John McCain so strongly is that he really has had a record of bipartisan accomplishment in the Congress and being willing to take on interest groups, including ones within the Republican Party, if he disagrees.

    Senator Obama — and that's what we need if we're going to really change Washington. Senator Obama hasn't done any of that. And, so, I thought it would be interesting to compare Senator Obama's record to the last Democratic president, Bill Clinton, who, no matter what else you say about him, he took on interest groups within the Democratic Party and worked across party lines to pass welfare reform, free trade agreements and a balanced budget.

    So, it was a special delight. I kind of — I wondered what President Clinton, if he was watching, was thinking.

    (LAUGHTER)

    CAVUTO: Well, that — you know, it's funny...

    LIEBERMAN And it got a round of applause.

    (LAUGHTER)

    CAVUTO: Right. That was the moment for me when I was watching. I said, I just heard Republicans applaud Bill Clinton.

    LIEBERMAN I know.

    CAVUTO: Hell has frozen.

    All right, so let me ask you a little bit about the fallout from this. Have you heard from any of your former Democratic colleagues — they're not former, you're the former Democrat — but and their reaction? They knew you were doing this. It was well-telegraphed, trumpeted, advertised.

    LIEBERMAN Right.

    CAVUTO: What have you heard?

    LIEBERMAN I haven't heard anything. But I can tell you in the lead- up to this — look, when I supported John McCain last December, people in the Democratic Caucus and in the Democratic Party in Connecticut were upset. A lot of them were not shocked because they know that Senator McCain and I have worked together on a lot of things, and — and we're friends.

    There was an effort, when the rumors started that I might speak at the Republican Convention, to really urge me not to do it by my Democratic Senate colleagues. And, you know, I just said, I support him. If he thinks I can help him by speaking at the convention, really to speak to the independents and Democrats watching, then I will — then I'm going to do it. I'm not go to spend a lot of time attacking Barack Obama.

    But I'm not kidding myself. I know that a lot of the Democrats are unhappy I'm here. I'm here, as I said last night, because country matters more than party, and I'm just so convinced that John McCain is the best for our country as president in the years ahead.

    So, I'm — I'm — with all that I have been through, I'm not thinking much about — you know, people ask me if they're going to take political action against you next year...

    (CROSSTALK)

    CAVUTO: Well, let's just say this. If Harry Reid were to offer you a croissant when you come back, I would think twice.

    (LAUGHTER)

    (CROSSTALK)

    CAVUTO: All right, now, what do you — do you worry, Senator, that, you know, let's say the Democrats build their majority...

    LIEBERMAN Yes.

    CAVUTO: ... in the House and the Senate, particularly the Senate, that then they're going to stick it to you?

    (LAUGHTER)

    LIEBERMAN That was a well-turned phrase. You mean the croissant?

    CAVUTO: No, the croissant will be just for the warmup act.
