I'm one.
Caine has no government/elected office experience - would make a good cabinet member.
Loved Bachmann, but I'm finding she often engages mouth before brain - may be a little thin on experience.
I don't like Perry's stand on immigration - but don't believe a more conservative 2012 Congress will let him do anything stupid.
Do you know what his stand is on 'immigration?' (He opposes illegal immigration, and he opposes the federal "DREAM Act" and calls it "an amnesty bill," and says that he strongly oppose amnesty.)
It might be informative for you to read THIS LINK - particularly about his signing of a bill to allow children of illegal aliens to have 'payment of in-state college tuition' - part of a federal government requirement.
Read further and you'll find that Parry is as frustrated as most conservatives are with the federal government not protecting our borders from illegal immigrants - and he rues the fact that Texas has to spend too much money using its forces to do what the federal government will not do.
