Contra Costa only has 44% of precincts reporting so far. They're populous enough to help! Right now 54-46 AGAINST
Los Angeles has only 65% of precincts in so far, unfortunately tiped 52-48 FOR - let's hope that WeHo hasn't been counted yet, that could shift things
Monterey reporting 34% of precincts, 52-48 AGAINST

Not the biggest county, but more votes against will help
San Francisco's almost fully in, so no help there, but they were 77-23 AGAINST in a nice populous area
Santa Clara 55-45 AGAINST, with only 53% reporting, and enough population to have an impact (thought not enough to swing it)
