Ben Tribbett (from Not Larry Sabato) final predicitions:

"In the Senate race, Tim Kaine has a healthy lead over George Allen who never seemed to grasp that it was no longer 1993. We are rating this as a "Likely Democratic" hold, and my best guess would be a Kaine margin of 7%.

In the Presidential race in Virginia, Barack Obama has regained the momentum and heads into election day with the advantage here over Mitt Romney. We are rating this as a "Leans Democratic" hold. If I had to guess margin, I would say around 4% of the vote.

It's quite possible for the first time in modern history that we will see Virginia voting as a state to the left of the decisive tipping point state elsewhere. This is because of the exploding demographics here. In fact, Obama should be going from a 250K margin to a 400K margin this year in Virginia, and the fact that he will be well short of that is a credit to the GOP's campaign. But without a national tidal wave, they won't be able to turn Virginia red in 2012, and it may be another generation or two until this state votes Republican for President again."
