For some reason, Prop 14's support has begun dropping, down to 57% now. I suppose the numbers don't really exist to flip it, especially since San Francisco County is 100% in now.
I think the first votes in were mail-in votes. Does California permit those to be counted before the polls closed (the first results were 10s of 1000s of votes from the big counties).
At 5000 precincts and 2 million votes it was still 60:40
The next 11,000 precincts and 1 million votes were 48:52
There are 6,000 precincts left.
Counties with a lot of precincts out include LA, San Diego, San Bernadino, Riverside, Alameda, Santa Clara. The strongest Yes area appears to be the Inland Empire, but that may be because they haven't got around to the walk-up vote.
Permanent mail voters might have greater share of participation by DTS voters, since they get sent a ballot. Any GOTV on election day are going to tend to be directed at party registrants.
DTS by-mail voters get sent a notice asking if they want a partisan ballot, along with a toll-free number where they can get information on which parties are permitting them to vote. So some aren't going to go through the extra work, and are going to get a non-partisan ballot, and will probably vote Yes. And even those who navigate the system are going to be upset at the hassle, especially if they picked wrong and couldn't vote for who they thought they could.
