I used to be a big time Deadhead growing up. Nuclear Disarmament, Farms Not Arms, the whole berkeley scene. But then I got a job, got married and bought a house. And then....Clinton happened..
As Ann Coulter proves, being a Deadhead, doesn't necessarily make one liberal.
I loved the Dead and went to every concert I could (even paid $150 a ticket to take a girlfriend to see them). I really enjoyed the whole "hippie" scene even though I politically disagreed with all of them.
Of course, I think it was different 15 years ago when I was in college because you didn't have the rabid anti-Bush sort of stuff. Most of them didn't care about politics, they just voted Democrat cause they knew that's what they were supposed to do.
