I am not an American but in this country we had enormous problems with fraudulent postal ballots and absentee ballots being "collected" by community groups from peoples houses so that it could be ensured they voted in the "best interests" of the community - which actually meant the community activists. I lived in an ethnic community and saw this personally. Such was the scale of the problem, the rules had to be radically overhauled. You, like us, already have all sorts of problems with voter identification, people with multiple registrations, dead relatives voting, your cat voting and voting boxes left in the trunks of cars. It does not take a genius to work out in a close run state that if getting rid of Trumpi is all that matters, falsifying some fake postal ballots is a good bet, especially if the race is close.
