I know a bunch of liberals, and they still like obama too.
I went out with a couple of guys over the weekend. One is a Dem, the other an independent who voted for Obama in '08. I'd characterize neither of them as "political", which is probably why we get along so well.
Talk *did* turn to politics, however, as we all agreed that our 401k's were taking a beating over the past couple of weeks.
The "independent" (and, more conservative one) said, approximately, "I voted for Obama because I thought he was different and I thought he could change the system. But it looks like he's just more of the same brand of BS politician. No way I vote for THAT again."
The Democrat agreed, though he said that he'd likely just stay home. "To hell with all of them." was his comment, approximately.
Me? I said nothing. They were doing such a good job of self-flagellation, that there was no more I could contribute.
I realize that this is just one anecdote. But I think that this kind of opinion shift is a lot more prevalent than any of us realize. Good news, IMHO.
