I try to avoid most political discussions. I feel I'm sufficiently informed in the areas that are important to me, and anything further is just frustrating or pointless, even if I'm talking to people I largely agree with.
That said, the coffee shop I frequent had a Bernie Sanders fundraiser today, and I stuffed $10 in the box. I'd never donated to a primary before, and the last time I donated to an election was in '04 for the guy running against Bush. There are some key things I disagree with Sanders on (specifically his promotion of wind and solar power while excluding nuclear), but I'm in the "this is our one chance to elect someone who values voters as people and not votes" camp.
But if Clinton is the Democratic nominee, I'll vote for her in the general. When I voted for not-Bush in '04, it was because he wasn't Bush, not because I supported him. But if Clinton is the nominee, that won't be the case. I don't dislike Clinton, I just like Sanders more.
