What's wrong with paper ballots again? Serious question. In my area (northern MA), voters are given a ballot with a bubble next to each of the candidates' names. You use a marker to fill in the bubble next to the candidate you want to vote for, like 6-year-olds manage to do all the time on multiple choice tests in school. Then it gets read in by a machine, leaving a paper trail just in case. How are these electronic…
Just because you never see this issue doesn't mean it doesn't exist. It's just that the ambiguous ballots don't matter in the vast majority of elections so no one cares.
I'm not saying computers are better than paper. They each have trade-offs.
