I see what you're saying, but "true believer" types are even worse. Romney may not have a lot of his own beliefs or principles, but Ron Paul and his supporters are clearly willing to put belief ahead of everything else. If Ron Paul was in charge, it's pretty clear he'd do whatever he wanted regardless of what the public or anyone else said, because he BELIEVES.
Romney may be sort of like a used car salesman, but at least you can work with someone like that.
I thought about all that and I still don't care. What Romney believes could be a lot worse than what Paul believes. I know what he believes and it doesn't scare me. It will never happen.
