Why can't all politicians be as candid and open as Ron Paul?

I know exactly where he's coming from in every vote he casts because he tells me so. If he gets asked a question in an interview you can bet he'll answer it. When he talks you feel like he's actually saying something unlike other politicians who talk a whole lot while revealing nothing. Despite what you think of his views, at least he tells you what they are. I don't think any other politician is as candid. It's a testament to the popularity of his ideas that he even has a career in politics, being as open as he is.
