Ron Paul and Gary Johnson are the only two major party candidates I would consider voting for in 2012. If one of them runs, I doubt the other will.
Anyway, like Johnson, Paul would be better off starting in New Hampshire. SC isn't a bad state to target either, but the evangelical/Huckabee wing seems to really have a stranglehold over the Iowa caucus.
Seems that way. I can't see Johnson winning Iowa (or South Carolina for that matter), and he definitely won't finish ahead of Huckabee; same for Paul.
