Seattle Times computer whiz Justin Mayo has whipped up a map showing how the primary election for King County executive broke down by precinct.

As you can see (click map to see large pdf version that allows you to zoom in to specific areas), a red tide of support for Susan Hutchison dominates the suburbs and rural areas that surround Seattle, a stronghold for Dow Constantine. The King County councilmember dominated his home turf in West Seattle along with liberal bastions in the University District, Capitol Hill, Wallingford and Vashon Island.

Constantine faces Hutchison in the Nov. 3 general election.

In the primary Hutchison won 33 percent of the total vote and Constantine got 27. Fred Jarrett, Larry Phillips and Ross Hunter split the remainder, almost evenly. Jarrett and Hunter won pockets on the Eastside, where they represent voters in the state Legislature. Phillips won parts of Magnolia and Ballard, which he represents as a King County Council member.

Hutchison did win some Seattle precincts, including six around her Laurelhurst neighborhood. But, she lost her own precinct by seven votes, 50-43.
