Once again, watch the trend line. Rasmussen Reports has a fresh poll out today on the Washington governor's race, but what's useful is how it compares to earlier results.
In late February, Rasmussen had Democratic incumbent Chris Gregoire at 46% and Republican challenger Dino Rossi at 47% - essentially a tie. In late March the results were nearly identical, except that Gregoire now led by one point. This week (a month and a half later), Gregoire is reported to have opened a 52%-41% lead over Rossi.
