Arrogantly assuming you know who is "electable" at this time is nonsense.
At this point in 2003 Howard Dean and Weasel Clark were the Democrat front runners.
At this point in 2007 the front runners for the GOP were Fred Thompson and Rudy Giuliani.
It is this arrogant assumption of the infallibility of their feelings that makes base GOP voters remember just how badly the GOP Establishment has screwed up everything since 2004.
I base who I think is electable on national and state polls, and a little bit on gut feeling.
If Cain or one of the other more conservative candidates jumps way up in the polls, I might shift my support to them, but until they do I am sticking with the most conservative of the frontrunners.
I could never support Romney under any circumstances though because I will never support someone that is pro abortion, and Romney was until he started running for president, and I just don’t trust that he actually ever swiched his support and I certainly would never trust him to select Supreme court justices.
