When the polls closed in California Tuesday night, June 7th, the report was that 100% of the votes had been counted, and Clinton won by 440,000 votes.
On Friday, June 10th, California Secretary of State
Padilla announced that over 2,400,000 ballots- mail-in and provisional, had not
yet been counted!
Precise turnout figures for this year won't be known for days because mail ballots postmarked by Tuesday will be counted if they're received in election offices by Friday. Los Angeles County alone estimated it had 570,000 ballots left to count.
Nearly 650,000 Californians registered to vote in the last 45 days before the deadline, giving the state a record primary election registration of 17.9 million.
