Holperin race -- super close or blowout? Tune in tomorrow

Of the two remaining Wisconsin races, the Jim Holperin is believed to be the one that the Republicans have the best chance of winning. And the polls are...conflicted. We have one Daily Kos/Public Policy Polling poll that has Holperin up 55-41, the other from We Ask America has it 51-49 Holperin. That's a big difference, so someone is going to look bad tomorrow. I do wonder why that second poll doesn't have undecideds.
