Btw... Jimmy Carter apparently already voted for Biden. Which again, shows why absentee voting / mail in voting is a joke. There is no f'ing way he's mentally competent enough to vote at this point. Yet, since it's not longer a requirement for you to show up and vote on your own, he gets to influence the vote in a crucial state. Complete BS.
There's no reports that speak to his mental capacity that I've seen. There's some conflicting anecdotal stories that say he's having trouble speaking, but that's to be expected at his age.
As far as absentee/mail-in voting, that's been around since the 80s at least and is used by our soldiers and other specific and legit situations (disability, hospitalization, travel, college, etc.). There's absolutely nothing wrong or illegal about it (when used correctly). And to get a ballot you have to register way in advance and show ID/legal documentation and explain why you can't or won't be able to make it to the polls. It's not like you can just get one out of a vending machine.
I used them every year I was in college. I used it one year I knew I had to work and couldn't make it to the polls and back in a reasonable amount of time as I worked out of town and in a different county. My mom did it often as getting her to the polls required assistance with getting dressed, out of bed, and ready. This could often take 2 hours and then she still had to drive to the polls and back, and then have assistance getting back into bed and resettled. But sure, big joke for her to exercise her God given rights.
