Reports KING 5 television:

In KING 5’s first head-to-head poll between former TV news anchor Susan Hutchison and King County Councilmember Dow Constantine, likely voters picked Hutchison over Constantine, 47 percent to 44 percent.

That gap is within 4.2 percent margin of error for the poll, conducted by SurveyUSA, which asked 557 likely voters who they would pick if the election were held today. Ten percent of voters are undecided, making any outcome possible.

Constantine's campaign to reveal Hutchison's right-wing roots could turn the tables. In the poll's breakdown, one-third of Democrats still support Hutchison. Those Dems, who are likely to switch sides as Hutchison's conservative history comes out, make up 46 percent of the vote. Meanwhile, only 21 percent of Republicans currently support Constantine, and could shift to Hutchison, but they represent just 26 percent of the electorate.
