Carson is the better of the two candidates. I consider Carson as a person--as well as his policies--to both be better than those of Trump's. For example, I don't understand why Trump would attack Cruz over what he's done as a senator if he's a true conservative (and I'm saying this as someone who previously didn't like to hear people say that Trump's not a true conservative!), and I currently prefer Carson's flat tax over Trump's tax policy.
Ben is not a Clinton, a bush, a communist, or a jerky racist businessman, and martin o malley, well he's okay, but he's not what we need, what we need is someone who is not part of the whole bush coups which Obama is, he is a cousin of the Bush's.
