Ron did well, but he still suffers from all the same issues he did last election in terms of coming off as "presidential". People have been saying he's since become more polished but he wasn't tonight. Johnson was also weak on that front, but less so. I liked everything Johnson had to say. He seems to be the most straight up libertarian of the bunch including RP, although Ron seems to have a much more sophisticated understanding of things like economics and foreign policy.
Depending on how things shake out I'll vote for RP or Johnson in the primary. It pretty much goes without saying that the rest of the GOP candidates are typical politician dbags and can all go to hell. I love that after all the rah-rah-rah of "never again" talk after the 2008 defeat from the GOP they've managed to produce an even more batshit insane, social conservative freak show than last time. Obama's administration basically handed them the win if they could only produce a single reasonable, inspirational fiscal conservative that doesn't make things like putting intelligent design in schools a priority.
