With Election Day imminent, the final PPP survey of the cycle shows Republican Dino Rossi leading Sen. Patty Murray (D) by two points — 50 to 48 percent — Rossi’s first lead in a PPP poll this year.

Get this: Among the 76 percent (!) of voters who said they have already turned in their ballots, Rossi leads by five — 52 to 47 percent. The remaining 24 percent support Murray 51 to 46 percent. But will those hold-outs be motivated enough to vote? Murray better hope so, because as it stands, she looks set to get swept up in the coming wave:

“A lot of the time in a wave election all of the close elections end up tilting away from the party in power at the end,” said Dean Debnam, President of Public Policy Polling. “If that proves to be the case this year Patty Murray could be one of the victims of it. This is going to be a very close race that we may not know the outcome of for several days.”

A source familiar with the Rossi campaign echoed this sentiment in an e-mail to BATTLE ‘10:

This is a classic year for the adage ‘the incumbent gets what the incumbent gets’ in the pre-election survey. An undecided voter is VERY unlikely to break for an incumbent, especially an 18-year Democrat incumbent, this year.

There is a lot of confidence in the Rossi camp, and a lot of despair among liberals. Even Chris Mathews and Howard Fineman are predicting a GOP win in this race.
