Dems will control both Houses of Congress. According to MSNBC, the Associated Press is reporting that Conrad Burns has conceded the Montana Senate race to Senator-elect Jon Tester. Virginia Senator George Allen is expected to do the same at 3 P.M. today. From the New York Times:

Senator George Allen is expected to concede his re-election campaign against his Democratic challenger, Jim Webb, later this afternoon, according to two Republicans connected to the Allen campaign...

Many election analysts concluded that Senator Allen was unlikely to close the roughly 7,000 vote margin separating him from Mr. Webb, who has already claimed victory. And the Associated Press, a widely accepted authority for calling elections, agreed on Wednesday with Mr. Webb, declaring Mr. Allen, a Republican, the loser. A Webb victory gives the Democrats control of the Senate, with 51 seats.

A senior Allen adviser who spoke on condition of anonymity said on Wednesday that if the margin did not narrow significantly, Mr. Allen would not challenge the result.

It's just about over.
