Nate Silver's Final Senate Forecast

Larger interactive version here. Silver gives the GOP a 9% chance of winning the Senate majority. Keep your eyes on West Virginia, Washington, Nevada, Colorado, and Illinois. Alaska is really a mystery, what with Murkowski's write-in campaign and the GOP backing away from its own nominee Joe Miller. Democrat Scott McAdams is only polling at 27%, but in a three-way race with the two GOP candidates splitting votes, there's a slight chance we'll see a nice surprise.
