Senate Ratings

May 27, 2010 · 3:24 PM EDT

Former state Sen. Dino Rossi’s (R) entry into the race against Sen. Patty Murray (D) brings Washington’s Senate seat into play. Murray appears to have a narrow lead in the polls and Rossi brings some high unfavorable ratings to the table after two losses in very competitive gubernatorial races. But this is now a real race. For now, we’re rating the race as Narrow Advantage for Murray and the Democrats.

While events between now and November will affect the outlook for November, the GOP seems most likely to net 5-7 Senate seats, with a 8-seat gain certainly possible (but still short of the 10-seat gain the GOP would need for control). That means Democrats are likely to retain control of the Senate, but at a dramatically reduced level.

Here are our latest Senate ratings.
