One part of the white Obama vote is as you describe.
A perhaps larger part of his white vote is actually considerably wealthier than the average and voted for him out of either white guilt or ideological agreement.
It's only the middle of the white economic scale that voted for McCain. Or more often (like me) for Palin.
Actually you have hit upon a wordage that can be used...
“White Guilt”
I would love to see this explained on Fox coming up in the next hour, or for Glenn Beck to harp upon it, thats a good point because its something that Obama has monopolized to his advantage, question is how far must it go? How may years or generations must we consider this “White Guilt”?
Personally in my view Obama was a new player in the baseball team that managed to get at bat, he hits a couple of grand slams early in the season but every appearance to date he has choked up, fouled out and struck out.
And now the team is losing its chance for the playoffs, all because of one player that everyone thought could keep on hitting the Grand Slams.
In other words, the bluebloods and deadbeats voted for authoritarian government.
As for those of us trying to work for a living, well that’s just not fashionable any more...if you don’t have a trust fund or a welfare check, what good are you?
