A Drake University law professor, Neil Hamilton, reported confusion with the new touch-screen voting machines, which are designed to help voters with disabilities who can’t use a pen to fill in the ballot ovals.
From the Des Moines Register.

Hamilton, who voted in Dallas County, said the electronic print-out of his vote showed a different candidate than the name he’d touched on the screen.

“I went and told the officials, ‘You’ve got a problem. This isn’t who I
voted for,’” he said.

Election officials marked two of Hamilton’s ballots as spoiled before he was sure his third ballot had been tallied correctly.
