Must Obama Change Voters with Racist Mentality?

Is the onus really on Obama to cause White voters -- who say that race is an issue in their vote – to vote for him? Is that what he has to do? He has to change years, decades, and centuries of backwards thinking in America to win the presidency??? It’s not Obama who can’t close the deal. It’s the 10% or so bigoted Americans who won’t allow him to close the deal.
