I'm not american, but if i was, i would vote for him over any sort of republican. These guys always sound like nutjobs, why would people vote for them? Even if you don't like everything that Obama did, is it really worth it to vote for republicans just because of that, when these guys might do even worse?
It's the same thing in Quebec here, i dont always like what our prime minister does, but i still think its better than the alternatives : You either have the party obsessed of separating from Canada(and who is losing members every month or so) or the newly formed party who just say "We'll see" to every questions.
