I'm of the opinion that Sanders is trying to bring attention to issues ignored by "electable" politicians. He knows that being a self-proclaimed socialist makes him massively unpopular in some parts of the US.http://www.slate.com/articles/news_...ndependent_voted_against_gun_control_for.html
So, Bernie Sander has voted against gun control. That's a plus in my book, he'll respect my second amendment rights. Unless the gun grabber lobby gets to him.
That being said, I imagine lobbyists will ignore him on the grounds he's too much of a long-shot.
