Mike McGinn at 49.78 percent, with 65,172.

Joe Mallahan at 49.38 percent, with 64,657.

That's a difference of 515 votes—a slight gain for McGinn over yesterday's 462-vote margin for McGinn.

McGinn got 49.77 percent of today's drop; Mallahan got 49.56—a reversal of yesterday's trend, which favored Mallahan 50.92 to 48.67. That's good news for McGinn.

McGinn received 12,934 votes in this latest batch. Mallahan received 12,881, a difference of 53 votes. So, still a virtual tie.

(As a political junkie friend points out: Today things are "trending McGinn." Yesterday, they were "trending Mallahan." And had the county counted all 46,000 from yesterday and today all at once, we'd see a net increase 395 for Mallahan since election night, and we'd all be saying "things are trending Mallahan" again.)

Bottom line: I don't think we'll know the outcome of this race for several more days, if not longer.

Also, King County Elections is only reporting an additional 27,151 votes today, and 25,989 in Seattle (the difference is because some votes were write-ins). So there are still many thousands of votes outstanding.

Not to mention: 4,700 ballots have been challenged because the signatures on their ballots don't match the ones King County Elections has on file. So if things stay as close as they are currently, I imagine that both Team Mallahan and Team McGinn are gathering their lawyers for a potential legal challenge.
