Seattle swung to Biden, along with pretty much every municipality in King thanks to consolidation of the extremely high level of 2016 third party performance (lots of places this was 8-12% of the vote.
It's also clear that there were South Seattle minority-heavy precincts that swung to Trump, sometimes quite dramatically. Precincts that voted 80% + Clinton, with Trump <10% ended up 75-25 at worst, or 80-20/high teens. Also notice how traditionally very democratic SeaTac didn't crack 70% for Biden?
With King county certification this past Tuesday, here's how King County cities voted (Bothell, Pacific, and Auburn results are inclusive of their appendages into Snohomish/Pierce counties):
Basic takeaway is that the Eastside now votes like inner suburbs (quite a few >80% Biden precincts in Shoreline/Lake Forest Park/Redmond(!)/Mercer Island.

I made a map of King County. Nice to know someone broke the results by municipality!
Great job! I wish we had a swing map compared to 2016 and 2012...
