Three polls of Washington's U.S. Senate race released in the last 24 hours have different numbers, but actually conclude the same thing: The race is very close.

Rasmussen Research late Thursday had the race at 47 percent Dino Rossi, 46 percent Patty Murray. It's a survey of 750 voters, has a margin of error of 4 percent. So in other words, it's tied, although Rasmussen notes that Murray was up 49-46 in a similar poll last week.

Also on Thursday, SurveyUSA had the race in an actual tie at 47 all in a poll it did for KingTV.  It's a survey of 678 voters, with a margin of 3.8 percent.

At noon today, the Washington Poll, conducted by the University of Washington, had two figures from two sets of 500 voter surveys. For all voters, they  have the race at 49 percent Murray 45 percent Rossi; among likely voters, they have it at 51 percent Murray, 45 percent Rossi. Their margin of error is 4.3 percent for each of the 500-person surveys.

More on the Washington Poll results, which asked about issues important to voters, later on Spin Control and Sunday morning in The Spokesman-Review.
