I am convinced prejudice will keep him, from doing as well in the election as polsters predict.
There's a lot of debate about this. Given that there are so many non-racist reasons one could give not to support Obama, I don't see why people would decline to declare their opposition to a pollster out of fear of being seen as racist. Also, Harold Ford did just about the same as the pre-election polls predicted when he ran for Senate in Kentucky last cycle.
How race may or may not affect how undecideds break going into the voting booth is another matter.
I do think, though, that New York is safely in the Obama camp. You won't see much in the way of presidential ads except as spillover from other markets which may be in play.
