CHARLES KRAUTHAMMER: It was an amazing debate. If the Democrats were engaged in skirmishes with the occasional subtle jab, and if the previous Republican debates have been World War I or II, this was thermonuclear. I have never seen as much personal attacks, as much high temperature attacks as we saw in this debate. And I'm not even sure you can judge the debate or who won or who lost on the actual sound bites,who won this exchange or that, it was the tone. I think that if you counted up the number of times the word lie and liar was employed, it would exceed the number of times it has been used in all previous debates.
