I believe that the Bradley Effect is in play with EVERY poll that we are seeing these days. McCain will win PA, and OH and VA, for that matter.
This isn't a conversation Whites/Hispanics have with each other. The polled were exposing their own racial bias to the pollsters.
Again, that is wrong, but it is still reality in America and has to be factored in. Ya can't force social integration on people and Blacks like a Colin Powell, with a tremendous resume' would have a much better chance of overcoming racial bias, not someone from the neighborhood.
