Bernie must be dull as hell in his personally life. He literally isn't interested in anything that's not directly related to economics.
It actually wasn't economics that first got Bernie interested in politics. It was the fact that a political party resulted in his father's family all being killed that first got him interested in politics.
Stop. This isn't even a criticism of Sanders' politics, it's a criticism of him being a dull person, which he is. Are you this obsessed with Sanders that you can't fathom anybody insulting him?
