Answering my own question:
Looking at the counties with the most uncounted ballots and knowing what we know about the electorate geographically, it doesn’t look good. The one gleam of hope is that L.A. Co. is Cooley’s county and there over 200k uncounted ballots there. Normally that would be a bad thing for a pub, but L.A. Co. has elected Cooley D.A. for a good, long time, so maybe those votes will squeak his way.
But overall, I’m not real optimistic. There are a whole lot more uncounted ballots from lefty areas than there are from the red areas.
