THAT’s the 64k question... Folks keep saying that most will break McCain’s way... What if they just stay home?
Then, I'd guess, we'll be in a bit of a pickle.
However, remember that these are supposed to be "likely voters", meaning the pollster thinks they will actually go to the polls. I feel, based on what we saw in the primaries, that this pool of undecideds will vote and does not want the pollster to know for whom they will vote.
