I come from a large family of black Democrats who all voted for Obama in 2008. When I went home to California to visit in April 2010, all traces of their love affair with The One had vanished.
When the subject of politics inevitably came up, I was astonished as they all sat and quietly listened to me state my views on the (then) current political scene. It was unnerving. It hadn't been that long since they would have ganged up on me and shouted me down.
It's hard to say whether any of them are pissed off enough to vote for Romney, but one thing's for sure....the 'thrill' is long gone. I expect many (if not most) of them to stay home on election day.
By the way, welcome to North Texas!
