Remember that?

William Saletan in Slate today:

I can't stress this enough to Democrats who opposed the Iraq war. Terrorists killed 3,000 Americans on 9/11. The first thing Americans want to know from a prospective president is how he's going to protect them from such enemies. If you don't answer that question, nobody will care that Bush exaggerated Iraq's weapons of mass destruction or Iraq's connections to al-Qaida. The only difference voters are going to see is that one party is serious about getting those bastards, and one party isn't.
