Others have said it - he and John Huntsman (to a lesser degree) both seem to be the most realistic of the bunch of talking heads that competed for the Repub party nominations. Of course, Huntsman's out of the race because most neocons A - don't like Mormons and B - had a problem with him saying religion shouldn't play a big role in government, and that he has faith in science.
Paul seems like a genuine guy. I'd like to have a conversation with him; seems like someone with wisdom. Most of his ideas are ideals, so while I support some of what he says I know realistically he will never get elected. It's a shame too, probably would piss everyone off. We need someone like that in the USA - someone to shake up the dreary shitty status quo. Paul wants us to take our dicks out of countries where we don't belong. MURKANS don't like that.
Santorum is a fucking idiot. I don't even know why Amerika chose to do a piece focusing on that asshat. Typical neocon jibberish. But hey, at least we've got a funny alternate meaning to his name now.
I think the real solution to the problem you point out is that the United States, being divided along several cultural lines, simply has to fracture in some way. Maybe not completely, but there needs to be some kind of parallel living and empowering of local communities.
I'd be in support of a fracture into regions (say, Northeast, Southeast, etc), or of a fracture into 50 separate countries. Either way, the entity known as the USA is damaged beyond repair.
