About Ron Paul

So far, I believe that Ron Paul is the best candidate for president at this time. I haven't heard any real criticisms that aren't poking and prodding at things that don't matter.
I'm new to this board, and I am not educated in politics or politically savvy. What are your reasons that I should NOT vote for Ron Paul?

The only downside I can see to Ron Paul is that he is religious. Unfortunate that an otherwise consistently rational and intelligent man can take something, anything, on faith. But yes, the only negative points the opposite can come up with are petty, irrelevant things like him being popular on the internet the way no politician I know of is, which is apparently a bad thing.
