Obviously, this race is just getting started, but in Washington state, Republican Dino Rossi starts out just 4 percentage points behind incumbent Democrat Sen. Patty Murray. I wouldn’t bet the ranch on a Rossi win, but the ingredients of an upset appear to be assembling: The electorate is roughly split evenly on whether the state is moving in the right direction; only 33 percent describe themselves as certain to vote for Murray; the economy and health care are the top issues on the electorate’s mind.
