(CNN) -- "Larry King Live" has devoted lots of time to the views of all the presidential candidates and their backers. Last week, King spoke to Sen. Hillary Clinton, and there's a standing invitation to all three candidates to appear as guests on his show any night.
TV host Larry King interviews documentary filmmaker Michael Moore on Wednesday.
On Wednesday night, King spoke to Oscar-winning documentary filmmaker Michael Moore, who in April endorsed Sen. Barack Obama. Not surprisingly, Moore didn't hold anything back.
Larry King: When you were last here in February, you said you had opinions on the race, but were not endorsing anybody. What changed?
Michael Moore: Well, I think that the whole movement behind Obama is very impressive. And I think it's a good thing for the country. As far as Obama as a candidate, I think that this is a very decent individual. And I've been just impressed through the various debates as to how he's handled himself, how he has responded to the issues and responded to people.
King: What about how he's handled the Rev. [Jeremiah] Wright thing?
Moore: Jeez, you know, I mean I go to Mass still. I'm a practicing Catholic. I've been that way all my life. But if I had -- if I had gotten up every time I heard a priest from the pulpit in my travels around the country say things like I've heard them say, that birth control is a sin, that women should not be priests, that women should have a different role in church ...
King: You'd be walking out all the time?
Moore: I would have been walking out so much -- that would have been so much aerobic activity for me ... I wouldn't look like this.
King: OK. You announced your endorsement of Obama on April 21 in a letter on your Web site. You also slammed Hillary Clinton. ... Why so rough?
Moore: Well, I supported her run for Senate. My wife and I contributed to her campaign. But the huge disappointment was when she was presented with an opportunity for a moment -- a profile in courage moment in October of 2002 -- to not give Bush the authorization to go to war, she voted for war. And she continued to vote for war for the years after that ... and I'm disappointed in that. But when I said [I was] 'disgusted,' that came with the ABC debate. When she threw out [Nation of Islam leader Louis] Farrakhan, when she said the word Farrakhan and Hamas -- to somehow attach that to Sen. Obama -- I just thought that was beneath everything that she used to stand for. And I think at some point, she's going to be disappointed in herself for having done that.

King: Are you so disappointed that you would consider, if she got the nomination, [voting] for [Sen. John] McCain?
Moore: Absolutely not. No, no, no ... most people I know are just going to stagger into the voting booth in November and look for the big "D" on the ballot. And it really isn't going to matter what the name is on there, whether it's ...
King: You think a Democrat's going to win?
Moore: Yes. ... We've been through eight years of misery. And it's not just the war, although that should be enough right there. But it's everything from what people are paying for gas now to our health care mess and everything else in this country that has just -- we've lost so much time.
King: Don't you think, Michael, that the Democrats [are] the one party that can figure out a way to lose this?
Moore: It's not about the Democratic Party. This has gone beyond that. That's what's so great about Obama is that he's not a partisan person in that way.
King: Do you think the Rev. Wright thing is over?
Moore: It's over when cable news decides it's over ... and when these networks come up with something new. I mean, I was kind of enjoying the flag lapel controversy.
By the way, Larry King, where is your flag lapel pin?
I don't see it on you.
King: Where's yours?
Moore: Well, I'm wearing mine. That's right. It's the world's smallest flag lapel pin. ... You just can't see it.
Moore: That's why you don't wear a coat, so you don't have to wear the flag lapel pin.
King: So you found me out.
Moore: Yes, that's right.
King: How are [Americans] going to turn out and vote -- what percentage?
Moore: I think we're going to have a huge turnout this year. People are crying uncle right now with what they've had to go through, and they're not going to want four more years of this. In spite of whatever concerns they may have about Sen. Obama, or if it turns out to be Sen. Clinton [who is the nominee] ... they'll put those aside when they think about four more years of what we have had for the last eight years. That's not going to go down with the American people.
King: Are your security guards ready to escort you out?
Moore: I actually have no security here ... the power of prayer protects me.
King: As a good Catholic, I understand that.
Moore: I do believe that. Thank you very much.
