Several states simply mass mailed ballots to addresses where a voter once lived. Some of These previous voters had moved out of state or to another county or voting district. Some had even passed away.
In these states there were no control measures.
Signatures were not able to be verified.
FYI. For the Nov presidential election,
NONE of the contentious Swing States that Trump contested, had mass mailing of ballots. Each of those states, the legal voter, had to request an absentee ballot, in order to get one.
Again, NONE were mass mailed to any old address on file. When a registered voter and citizen requests the mail ballot, they have to put on the request, where the ballot should be mailed....
There are MANY MANY MANY procedures in place in all states to prevent massive absentee voter fraud! A signature match isn't even a tenth of it!!!!
You can't get a ballot, unless you're registered to vote. many states verified signatures for the request, plus sigs on the ballot envelopes to the request and file signatures. The precinct can't mail out more ballots than are requested, and cant have more ballots returned than have been requested, and when counting the ballots, they can't have more absentee ballots counted than absentee envelopes received back....so no one can slip in a massive fraudulent stuffing of ballots.... Ballot stock paper is a certain paper weight, vote counting machines reject ballots lighter and not the proper weight..... These things prevent ballot stuffing!
Can an individual vote for their recently passed, dead mother? Maybe? But even they, are being caught through checks and balances in place.
I think every state, should allow mail in voting for any reason, for registered voters....this would solve a multitude of disenfranchisement sins, of the States....!!! It would cut long lines in the poorer neighborhoods, make it easier for moms to vote, with kids in tow, and easier for all of those hourly workers that can't afford to lose a few hours pay, to vote.....make it easier on all those citizens working non conventional hours....it would also save money on staffing for fewer days of early voting....
But, legislatures would need to institute laws forcing voting districts to keep their voter rolls clean...depending on the state, felons removed, and dead people removed regularly and systematically, only citizens on the voter rolls etc etc etc
