Rove: Obama won't get any undecided voters?

Karl Rove made a statement in passing on Fox news got passed over, but as time has passed I've decided it is the unspoken key to this election. Paraphrased: Whatever Sen. Obama is polling on election day is the percentage of votes he will receive. That's what happened in the primaries. It's important for him to be over 50%. In those states where he is under 50% he will be in trouble. It took a while for it to sink it, but what he is saying is that the undecided vote will go almost 100% against Obama
