I went with Herman Cain, with Bachmann as a followup. All the rest are either blatant RINOs, wafflers, wackos, or professional politicians to the point that I can't stand looking at them.
Cain, however, has weaknesses which are sure to be exploited should he win the nomination. He runs as a "problem solver", but what our president should be along with being able to solve problems is have a vision. He also needs to communicate and sell that vision in a way that does not ridicule and insult people (as Barry does), but inspires, uplifts, and challenges them.
I have not had time to look at Perry, though. Texans seem to roll their eyes when discussing him, and that tells me a few things. But I need to look at him more closely, especially if he announces his candidacy at the same time of the Ames straw poll.
