I'm not sure whether that has been proven. In any case, I think we should make it easier for people to vote, but also put checks in place to make sure that the votes are legitimate - and I believe we have the means to do so.
I agree but the problem with systems is they can be beaten. If we did it online for example someone could make a bunch of bots to vote for their candidate.
LET'S JUST BE HONEST ABOUT WHY REPUBLICANS DON'T LIKE MAIL-IN-BALLOTS; THE EASIER IT IS FOR PEOPLE TO VOTE, THE LESS LIKELY IT IS THAT REPUBLICANS WILL WIN, VOTER SUPPRESSION WORKS
