Oh i disagree completely. I think there is more fear of being called racist now than ever. I believe that rather than put up with the potential hassle of being called a bigot, people just SAY they like obama, or support him, just to get the pollster of their back.
The racial issue has become SO divisive in the last 4 years - thanks, Mr Uniter! - that I"m perfectly willing to believe people will now say publicly they like and support Obama, they'll say it in a phone interview, they'll say it to their friends, they'll even tell exit pollsters they still love him - but in the privacy of the voting booth, I believe they'll pull the lever for Romney.
I wouldnt' be surprised if even Bill Clinton voted for Romney!
