No, I don't think it's bad to have people like VDH in the Dem Party -- though I truly hope that party becomes extinct and has no one inside it within my lifetime.
I'm simply surprised. It's like finding a Rabbi inside the Nazi Party. Maybe he can do some good. Maybe he can persuade some Nazis not to be so anti-semitic. But the overall feeling is: "What's HE doing in THAT party?"
We need two parties(at least) and I want the other party to be filled with people that won't get me killed. That's not the case right now.
