As leaked to Slog earlier, and now reported on the teevee:

The race for Seattle Mayor is a virtual tie the day before the election, according to the final KING 5 News poll before votes are counted.

The poll, conducted over the weekend by SurveyUSA, has Joe Mallahan ahead of Mike McGinn, 45 percent to 43 percent, with 12 percent still undecided. With a margin of error of ± 4.1 percent, it’s anybody's race.

And:

Dow Constantine has surged ahead of Susan Hutchison in the race for King County Executive.

The poll... gives Constantine 53 percent of the vote over Hutchison's 43 percent. Five percent of voters remain undecided.
