Tonight Show host Jay Leno moved from entertainer to political commentator Monday night, blasting a "war on women" waged by the Republican Party and praising President Obama for having "compassion for regular people."

Revealing his political leanings while challenging guest Dennis Miller's slap at the president, Leno raised the abortion controversy of Missouri Senate candidate Rep. Todd Akin in attacking the GOP.

The debate between Miller and Leno:

DENNIS MILLER: I don't dislike President Obama. I just think that it's been an inept four years. And you know, I'm just calling it as I see it. I know you like him. What am I missing over the last four years? It just does not seem that good to me.

JAY LENO: Well, I think he has compassion for regular people. I think that's what -- I think if the Republican Party is missing anything, it's this sort of war on women, and, and compassion-

MILLER: War on women? With Sandra Fluke? She's 30, for God's sake. She's still in school. She wants me to kick in ten bucks a month for her birth control? Here, I'll give you ten. Just shut up for a second, okay? [Cheers and applause] This woman, Jay, the war on women, for God's sake.

LENO: I think it is. I think it is.

MILLER: The chick's like Moan of Arc, come on. [Laughter]

LENO: No, but Todd Akin was-

MILLER: He's an idiot.

LENO: He's an idiot, but he was saying what the platform is. And that's what many believe. I'm glad he came forward because it kind of showed - that kind of got pushed to the background and I think it shows what many believe. Because I think Romney is a good guy and a decent man. I just think he had to go all the way right, which I think will ultimately hurt him in the long run.
