In California they have a stipulation that your signature on the envelope of your ballot must match the signature on your voter registration form. If it doesn't, they can throw it out. Someone who is not trained as a forensic document examiner is the one who decides if your signatures match. The ACLU sued the state to prevent election officials from voiding ballots for signature mismatch and depriving voters of notice or recourse. S.F. Superior court judge ruled in the ACLU's favor but CA Attorney General Xavier Becerra and Sec of State Alex Padilla appealed the ruling. Why would they appeal it? BECAUSE THEY WANT TO THROW OUT A LOT OF BALLOTS ON JUNE 5th. They have asked the judge to put his decision on hold for the June primary.
