Australia has compulsory voting, which must change that dynamic a bit. Someone voting as multiple other people in different places is going to double up with the actual people, since they have to vote, so the incentive will be lower.

That said, NZ has a similar system without compulsory voting, and I've never heard of any significant voter fraud. We have decent voter turnout.

Yeah, compulsory voting is what makes it a viable way to detect fraud.

I was also mistaken somewhat when I said "paper ballots". There is certainly electronic voting in Australia, but the "authentication" aspect of just saying a name is still the same. It's essentially "trust but verify"

The US would hate the idea of compulsory voting, as the goal of Republicans is to make as few people to vote as possible.
