In what may be one of this year's biggest political upsets, Sen. Lisa Murkowski conceded the Republican primary to her opponent, Joe Miller, on Tuesday night.

Although the race for Alaska's U.S. Senate seat was very close with some absentee ballots yet to be counted, Miller's 1,500-vote lead was enough to convince Murkowski to bow out. 

"We all know that this has been a long week, a terribly long week," she said at campaign headquarters while conceding.

She said that while there were still outstanding votes, "I don't see a scenario where the primary will turn out in my favor, and that is a reality that is before me at this point in time."
 
Miller's victory puts another win in the column for the Tea Party and former Alaska Gov. Sarah Palin, who both backed the little-known conservative lawyer. Miller will next face small town Democratic Mayor Scott McAdams in the November election.

"Do you believe in miracles?!" Palin tweeted Tuesday night. "Congratulations, [to] Joe W. Miller! Thank you for your service, Sen. Murkowski. On to November!"
    
Murkowski is the third sitting U.S. senator to be defeated in a primary before the general elections.
