McCain: Hey, I'm all in for this Republican tax cut plan!

I'd rather have to admit a mistake like this than have the thing fail because McCain confirmed my worst expectations of him. Looks like I'll be heading up to the counter here at Atomic Coffee in downtown Royal Oak to see if I can get that crow on a croissant. Then again, McCain is committing to vote for a tax bill whose final form we might not know. He'll support the bill that came out of committee yesterday, but will that be the final bill? If not, does McCain still support it? Or does he claim he was willing before some unforeseen tragedy forced him to revert to his usual sabotagy way?
