Never look at one poll. Real Clear Politics does a good job of tracking numerous polls and taking the average of them all. They use the following: Quinnipiac, Rasmussen, NBC, Franklin & Marshall, Purple Strategies, etc.
Undecided voters more often than not go to the challenger. If the incumbent is already at 50% or more then he is good to go in that state. If he is between 48% or 49% then he is probably OK. If the incumbent is at 46% or 47% then it is too close to call. If he is at 45% or lower then the incumbent is in trouble.
