More problems arise in California:
SACRAMENTO, Calif. — Some vote-by-mail voters may not get their votes counted in Sacramento County, officials said.
Elections officials said in some cases, voters who are registered to one party are writing in a candidate from another party. Officials said they began noticing the problem on Friday after elections workers began opening up ballots from vote-by-mail voters — which used to be known as absentee voters.It’s a problem that officials said they have seen in previous presidential primaries, but it seems to be a more widespread problem in this election — perhaps because of increased interest.
Of course, it could also be that with Optical Scan ballots, when voted at poll sites, the optical scan reader has a chance to spit the ballot back to the voter for error correction, but a mail ballot never gives this second chance to the voter.
