On fiscal issues and on civil liberties, RON PAUL is clearly the way to go. That being said, he has virtually no foreign policy and a 'head in the sand' mentality regarding the threat posed to us by Islamic radicals who wish ALL OF US dead.
Perry is a theocratic neocon, Romney is Obama Lite, Bachmann is hot-looking but otherwise she is nuckin futs and Santorum is so smarmy that I would not even buy a used car from him. Gingrich has some great ideas, but carries enough personal baggage to open his own Samsonite store. Gary Johnson has some good pro-liberty ideas, but his campaign seems to be floundering. Gov. Chris Christie, although no conservative, did well with "average joes" like me; but he wisely bowed out of the race earlier this week. It would not surprise me to see him run in 2016 if circumstances permit.
At first, I was not sure about Herman Cain -- but the more I see him on TV, the more I like him. He is able to hold his own under media scrutiny and does well when shoots from the hip. His "9-9-9" plan is not perfect, but it is a far cry better than what we have now. Now that is a black man I could support to be our next President!!
In a nutshell, ANY of them would be preferable to Obama.....but I want to vote FOR someone, rather than AGAINST the other guy.
