Ever since
california.ballottrax.net has been logging votes (this is #11), we have never had a ballot rejected (see pics).
This election, the two registered (R) ballots were sig rejected, and the (D) ballot was accepted. Until someone told me to check, I was unaware they were not going to count our ballots. I was not notified.
~90% of California ballots are VBM (mail % - see right side column), so this is a vulnerability in the election system. Note that the California Democratic Party spends millions to assist curing of (D) ballots each election.
This might be what Newsom called "Break The Glass" to stop Republicans from getting into office. But it might be a wild coincidence, with under a 10% chance of being legitimate.
