A new GOP poll shows Dino Rossi leading Sen. Patty Murray among “likey voters” — 47 to 46 percent. Among those determined to be “most likey” to vote on Election Day, Rossi leads 50 to 45 percent.

Rossi also has a slight edge in favorability. According to the poll, 47 percent of likely voters view the Republican favorably, compared to 44 percent who view him unfavorably. Murray’s rating is evenly split 46-46 favorable/unfavorable.

A separate, independent poll released over the weekend that had Murray leading 50 to 42 percent. Polling has been all over the place so far, and complicated by the prevalence of mail-in voting. The only safe conclusion to be had right now is that this one is definitely going down to the wire.
