I don’t think many “leftist whites” will vote for Obama this time; their utopia hasn’t materialized, and they are struggling along with everyone else.
Despite what many think, OWS is not a bastion of support for Obama; they feel deceived by him, and many are still looking for their first jobs. They probably won’t support a Republican, but they won’t be fooled again by the Kenyan Pirate. I think the only “leftist whites” in his corner are homosexuals and public school teachers.
Even blacks have a lot less incentive to vote for him, and I’m sure they are a lower percentage of the electorate now than they were four years ago
Being that I am surrounded by leftist whites much of the time, they will indeed be pulling the lever for Obama again. Anyway, fashionably liberal whites in NY and NJ are irrelevant as both states voting for Obama are foregone conclusions. What matters are swing voters in Ohio. Colorado and Virginia.
Your points may have some validity. What they don’t have is anything to do with the Zimmerman shooting. Obammie may have trouble in this election (I profoundly hope so.) He will not have any more trouble because of the Zimmerman shooting and his stupid comments about it. I believe he will have less trouble.
