I believe there are a significant percentage of whites voting for bho out of guilt or what I call the Michael Jordon factor. Yes, I believe there are many whites who are so ill informed that they think bho is some type of MJ of politics. The blacks are equally as bad as they see race only which is not a good reason at all for casting a vote.
Like I said above, this is the type of poll results you get when you question 12% more dems than Repubs, do the math.
