You can bet this is going on in Texas, Arizona, Florida, and North Carolina.
Early voting in Palm Beach County, FL, you need ID. They have computers that check that you are registered and then print out your specific ballot. The only way you can vote more than once is if you have more than one ID and are registered in more than one place. I know a guy who sometimes goes by his middle name and other times by his first. He’s lived in several apartments in the area and is a liar and a real creepy lefty who visits the dark web. 6 years ago I overheard him talking to someone about where he voted early, then on Election Day we came into work with a sticker saying “I voted today!” I questioned him about it and he treated me as though I was crazy. Typical dem.
My son is a college student in the midwest. After mailing his absentee ballot request to Montgomery County, Texas, and getting no response from the county, he called them and asked where his absentee ballot was, when did they mail it to him and when could he expect it in the mail so he could vote. They told him they hadn’t received any request from him and he was out of luck since his request needed to be postmarked before October 26. He used the expression “disenfranchised voter” and reminded them that he had followed all the rules, on time, and they had failed to deliver his ballot. They said they would call him back in half an hour. 30 minutes later they had miraculously “found” his request for an absentee ballot, blamed a “clerical error” and said they would overnight a ballot to him.
