I make of it the same that I do of the Trump swing in Los Angeles County. A nothing-burger when you look at Biden's record performance.
Biden had the highest percentage of any candidate in SF with the second-biggest margin in SF history against a candidate who had the second-worst percentage for a runner-up. The only runner-up who did worse than Trump 2020 was Trump 2016.
The swings in California are some of the most overblown takeaways from 2020.
I find this to be increasingly problematic with columnists who want to compare NYC swings to LA Swings. Trump had the second-lowest percentage in modern history in LA County and Biden the second-best. In NYC, Biden had the worst Dem performance since Kerry '04. I wonder, to what extent, is incumbency in the results with Hispanics. Obama performed better with Hispanics in 2012 than 2008 in NYC, as well as Bush 2004 compared to 2000, and now Trump.
The NYC swings are also overblown.
