I regard it casually because it's statistically negligible. I usually post this link in threads about vote-by-mail where people bring up fraud, but it applies here too:
The (elected, republican) secretary of state audited the 2016 election and found 54 cases -- out of 2+ million votes cast -- of what's generally called "voter fraud," most of which were people voting in Oregon and in another state.
Oregon is entirely vote-by-mail, so there's no way to show an ID.
Remember, how you voted is anonymous, but who voted is known to the government agencies. They can and do analyze that. Voter fraud is not a meaningful problem.
Not even an American but this number is convicted people for voter fraud. It's not even a study or some intelligence agency estimate, so you're dishonest here.
Source? If I were going to commit fraud I sure as hell wouldn't do it while taking part in a study. Curious how that is dealt with.
Of course I know about the related talking points of the other side, I just think it's curious that people regard "double spending" votes so casually.
