You are assuming that there will be only one choice. That's one of our biggest problems. Allowing the illusion of the 2 party paradigm to control your options.
Personally, I'd take Ron Paul out of any of the ones you listed. I voted for him in '08 and probably will again in '12. And please don't throw the 'Republican' or 'Tea Party' labels around with him. He rarely votes along with his own party and they often go out of their way to disenfranchise him. Also, I've heard him say how he refuses to align himself with the Tea Party because most of them are 180 degrees opposite of what he stands for.
By the way, I used those words you quoted because both Bush and Obama have proven over and over and over again that they totally fit what they mean. It has nothing whatsoever to do with party affiliation as you seem to assume. I don't play those games. Unlike too many Americans, I don't view elections as just another game such as football. I couldn't care less which party any candidate belongs to. It's all about they themselves, what they've done and what they have to offer. I'd love to have Ron Paul for president and Dennis Kuncinich as vice president.
