Sorry, to answer the question requires a spine if you are a Republican with Libertarian leanings (or vise versa) as kkkkk is. It takes a man to state the obvious, pretty much the whole field of Republican candidates are shit. I'm not that familiar with Huntsman, but based on this he does seem to be the least crazy of the bunch:

Huntsman professes a firm belief in science, rejecting the notion that faith and evolution are mutually exclusive. In response to Rick Perry's creationist world view [95], Huntsman warned that the Republicans should not become the "anti-science" party, and stated:
"To be clear. I believe in evolution and trust scientists on global warming. Call me crazy."[96]
"For GOP to win, we can't run from science. (Sep 2011)"
I think you have the best answer to the question so far Rob, but of course he's not very polling to well right now. Probably the biggest strike against him is that he is a Mormon.
You guys also pretended to consider voting for McCain... and that he was "cool" (at least around 2000 and 2004 and as long as he bashed fellow republicans now and then), but then decided he completely sucked once he got the nod (gramps! mcSame!). Keep pretending!
