I didn't really know that much about the guy before moving to VT. Since I've been here I've heard a number of interviews with him on NPR - have to say the guy strikes me as pragmatic, intelligent, communicative, and focused on good governance. Can't say I approve of and support all his positions 100%, but policies aside he's clearly not an empty beholden to political or religious dogma like those across the isle. The good outweighs the bad with him by a large degree IMO, so yeah, I'd give the guy my vote. He's a staunch supporter of the separation of church and state, women's reproductive rights, hates free trade, is serious about education and the well being of children, realizes that fossil fuels need to be phased out, and has a big problem with corporate money being seen as free speech. Sounds pretty good to me, although I disagree on his gun views and some of his votes concerning corporate tax havens and loopholes.
It's funny though, I've witnessed coworkers who count themselves on the right disparage or mock him (nothing I'd call material criticism, just snarky talking points references) - not unlike how I've noticed some regard Elizabeth Warren. When actually hearing the views from the man himself, I'll hear "Damn, right on man!" "Why can't we have politicians like thatinstead of McConnell and Boehner?" "Hope Cruz never has to debate that guy!"
As an intelligent, mature, level headed diplomat I'd probably vote for him despite my differences on some of his views, simply because if the last seven years have shown me anything, it's that there are too many indoctrinated morons in D.C defending their careers and special interests instead of doing their jobs.
