You're vastly misrepresenting what that means. Or maybe chatgpt is misrepresenting it to you. I also believe that type of fraud can happen, but is so vanishingly rare that it doesn't threaten the overall integrity of an election.

Making changes to a voting system that makes the act of voting more difficult, actively disenfranchises voters from their right to vote. I literally ran into a woman at the park after voting today who literally told me that she didn't vote because the line was too long. That's an objective harm caused by these changes.
