We are not all mail ballots. Never have been.
However the majority do vote by mail.
I voted at my precinct per usual.
Yeah, your can still go to a “Voting Center” (FResno County name for the limited # of “polling places” now since COVID) and vote in person, but everyone in the state also got a ballot in the mail...(adds plenty to the possible vote fraud tally):
CA SOS: “County elections officials mail vote-by-mail ballots to all active registered voters. Any registered voter may vote using a vote-by-mail ballot instead of going to the polls on Election Day.”
