If Romney picks a RINO of any shape or form for the VP. I predict millions of Conservatives to stay at home and not vote. Watch this bastard though, he may just pull a McCain/Palin lurch to soothe the TP!
I suspect he’ll pick Santorum for VP. Santorum is an unappealing personality who won’t be any threat to Romney (who is also unappealing, but in a different way), a thoroughgoing member of the DC establishment, and will get Romney the social conservative vote. Santorum is a very ambitious man and would go for it in a heartbeat.
