There’s nothing more fun on FOX than seeing the rare sight of Alan Colmes standing up on his hind legs and exposing Sean Hannity for the idiotic, hypocritical windbag he is. But this latest smackdown over John Edwards’ affair has become one of my all-time favorites.

HANNITY: I’m not getting this. Explain to me and I’m wondering if you can’t keep the promise to your family, can’t keep your promise to your wife, you’re having an affair, you’re lying about the affair repeatedly, why should the American people trust you when you say you’re not going to lie to them? Why should we trust you?

COLMES: And by the way, that’s a great question Sean asks and so Amanda, if that’s true and you can’t trust somebody who had an affair. How can we trust John McCain to be President of the United States—he cheated on by his own admission on his first wife, he didn’t keep his martial vows, he didn’t keep his pledge to his first family…

HANNITY: Thirty years ago after five and a half years of being a POW.

COLMES: Excuse me Sean. You’ve had your chance to speak, I’m up. John McCain cheated on his wife, right. Amanda? So how do we trust John McCain? He cheated on his wife, why do you have a double standard and John McCain’s running for President? John Edwards is not. John McCain’s wife was in a car accident. John McCain’s running for President, what about his affair?

HANNITY: After five and a half years in a POW camp.

COLMES: That has nothing to do with it. So it’s OK to have an affair on his wife.

Hannity went on to endlessly repeat that McCain was a POW who got beat up all the time and Edwards plays with his hair and has a big house, implying that McCain, therefore, has the moral authority to cheat on his wife who had been disfigured in a terrible car crash and raised their kids for years while he was a POW.

Another great thing about this clip is that it really illustrates how Hannity operates and how truly stupid he is. All he ever does is find (or is told) 2-3 things he doesn’t like about a Democrat — like Barack Obama and Rev. Wright, or Michelle Obama saying she was finally proud of her country — then simply repeat those things over and over and over again even if they have nothing to do with anything. That’s why Hannity flounders around in the second part of the clip trying to explain how it’s wrong for Edwards to have an affair because he plays with his hair and it’s okay for McCain to have an affair because he was a POW. Instead of actually trying to answer why Edwards’ affair makes him unfit to be a trustworthy leader and McCain can have an affair and still be president, all he can do is repeat over and over again that McCain was a POW and Edwards had an expensive haircut.

Hard to tell if Hannity has always been this stupid or if all those layers of Thompson’s Water Seal on his hair over the years have finally ruined his brain. (And he makes fun of Edwards’ hair!)

If you want to learn more about how McCain cheated on his wife, lied about it in his book, married Cindy McCain five weeks after the divorce was final, and how it strained McCain’s relationship with the Reagans, the LA Times wrote a good article about it here.
