Bingo....This should never have been a questionable decision amongst the base (if the base was even really considered).
I have my doubts, big time.
If you believe the Perpetually Pissed Off is the "base" you are wrong. Most of these don't care if the nominee gets approved they just what to see a big rhetorical fight with lots of noise and screaming.
After almost five years they haven't figured out that that is not Bush's style.
