Kristol "Bush slaughtered him tonight" YIPEE!
I believe the defining moment was the genuine emotion and heartfelt principle that came through when Bush was asked about his faith and his wife.
Kerry, by contrast, came through as a complete cardboard charlatan. His answer about how he felt about his wife: "Well, I uhh, think this is a multi-faceted kind of nuanced matter...that I uh..feel is something that....yadeyadeya."
It was the perfect subject to illuminate the hollow and opportunistic nature of this man...and the nation saw it upclose.
