Obama Coming Back to Seattle for Murray

He'll be here on Oct. 21, for a free rally at the University of Washington aimed at getting out the vote for Democratic Senator Patty Murray.

For those keeping score, that's Joe Biden, Michelle Obama, Bill Clinton, and Barack Obama (x2) who have either come through Washington or are scheduled to come through Washington in order to help out Murray, whose seat could determine whether Republicans or Democrats control the U.S. Senate next year.

What it means: the race between Murray and Republican Dino Rossi is, as everyone's been saying, very close.
