Ron Paul is likable because he's so honest.

As for the rest of the Republican field, these guys are all like, "No I hate gays even more than you! I'll kill more people and terrorists than you! I think women who get pregnant by mistake should be sent to Gitmo!". It's a hate-on between the so-called frontrunners on the right while Ron Paul has preserved his dignity and integrity throughout. He's the only candidate on either side right now who is all about ideas, even if you disagree with some of them.
