Waffling?

Josh Marshall hits the nail on the head when examining Bush's decisionmaking:

"Indeed, I'm really not sure you can say the president is a waffler at all. His policy positions remain fairly consistent over time. It's not his positions that change, but his facts.

I'd almost say that the president -- or the White House, more broadly -- is something like the inverse of a waffler. He continues with policies even after the factual arguments upon which he initially justified them collapse entirely."
