NO VOTING BY MAIL
IIRC, to get an absentee ballot, you had to provide a reason for it. When I was in college, I used to request absentee ballots from my home county and had to put the reason being that I wasn't in my home county.
The ability to just request a ballot through the mail is ripe for fraud. Hell, my signature changes often, and I've been jammed up when going to my local polling location because my signature doesn't look like the signature on my voter ID. How could they possibly validate the mail-in ballot?
If Trump loses this election, it will be because of fraud. The Democrats have been perfecting election fraud for several cycles now. I suspect they're ready to pull the trigger in any effort to take this man down.
