"California election officials announced Friday that 99.4% of more than 15 million mail-in ballots were verified and counted in the November election, ......"
"Of the mail ballots, 86,401 were rejected,.....
195,783 divided by 715,833 is 0.27%. Which is slightly less than half of the state's rejection rate in the 2020 election.
Just kidding.
In order to vote, you need to be mailed a ballot (because you registered to vote) or go to the polls and have your name seen on the rolls there (because you registered to vote). You won't get that physical ballot or have your name on the rolls to be given a ballot at the poll unless you register.
To sign a recall petition, you need a pen. The signature gatherer will hand you one. Test it out, come out to SF some April when they are gathering signatures for ballot measures, and see if they even ask where you live or if you are registered to vote. I tell them "I live in Sonoma County" and they will say "well, you can sign it an then they'll check if you are registered". Because the signature gatherers are paid by signature. More handsomely by well funded campaigns, for example a bunch of rich Republicans trying to recall a "progressive" DA (Gascon is an asshole btw)
Yet somehow you think the rejection rate on a recall petition would be the same as in an actual election?
