“Who here has sent in their ballot?” Trump asked a crowd of more than 2,000 supporters at a rally in Greeley. The crowd replied with a roaring affirmative cheer.

Trump then asked, “When you send your ballot in, do you think it’s properly counted?” The crowd was quiet for a second before people realized that the correct answer was “No!”

“You can check on your ballot to make sure it’s counted properly,” Trump said. “You can go to [Greeley voting location] University Center and they’ll give you a ballot, a new ballot. They’ll void your old ballot and give you a new ballot. And you can go out and make sure it gets in,” Trump said.

“In some places, they probably do that four or five times, but we don’t do that,” he added.

Trump appeared to be unaware that Colorado law prohibits voters who have already sent in their ballots by mail from “voiding” them and getting a new ballot so they can vote in person.

According to the Secretary of State’s office, the statewide voter registration system reads a unique barcode on each ballot sent in by mail, a process known as “binking in.” Once a ballot has been read, the registration system logs a particular voter as having voted. After that happens, the system won’t accept a second ballot from that person under any circumstances, and won’t “void your old ballot” so you can vote in person, as Trump suggested.
