>Perhaps its because I've always leaned a bit to the left, and have reached the end of my rope with conservative crazies.

It's also because Bernie is one of the first candidates in recent years to build his campaign entirely on a policy platform. If someone asks him a leading question to get him into personal bickering for the sake of a sound bite, he tells them to go away until they have a real question. All he wants to do is debate policy issues.

So anyone can go ahead and disagree with him, but his meta-level goal is a fucking necessity: make politics be about policy again.
