I voted in my precinct in Sun City at about 8am. In the short time I was there, about HALF of the Republicans arriving to cast their vote were told they were listed as having already voted via an early ballot. This surprised them all, since they would not arrive to vote if they had already cast a mail-in ballot.
The conversations went like this,...
Staff: "Did you receive an early ballot?"
Voter: "I don't know." or, "Yes, but I didn't use it."
Staff: "Well, if you received it, you had to use it. Because it shows here that you already
Voter: "But I didn't vote yet. I never sent it in."
Staff: "Yes, but if a ballot was sent to you, you are put down in the records as having voted,
so as to prevent fraud by voting twice."
Voter: "Why would someone send me a ballot I didn't request?"
Staff: "Perhaps your wife ordered one for you."
Voter: "So I can't vote?"
Staff: "Oh yes, you can vote. Just step over to that table and you'll be given a provisional
ballot. They'll check those against the early ballots to verify you didn't already vote
and then your vote will be tallied."
I don't know if all the ladies in Sun City were ordering early ballots for their men, but there was what appeared to me to be an exceedingly large occurance of these surprised provisional voters.
P.S.: Arpaio also had his signature gatherers (probably posse) outside the polling place for his next run for sheriff.
