This is always an unpopular position, but I'm gonna raise it again anyway. If the US would just get with modern times and do their voting through a phone app, the results would have been tabulated and we would have known our next president 2 days ago.
We would also have had higher turnout, and less Corona spread.
And have disenfranchised somewhere between a fifth and a tenth of the population
2019 smartphone ownership stateside looks like it was about 81%. It's probably up now, but you'd still be locking a lot of people out. Something that could be done with regular cell phones would still cut out somewhere around one in 20 people. It's the old problem with getting the US up to modern times with a lot of things -- swathes of it are little better than a third world shithole, and are going to have trouble with infrastructure.
Having the option might not be the worst idea, though. I'd rather we just do automatic registration or somethin' (if you're a citizen of age you get the vote, flat out, no conditionals, no registration, no way to take it away or deny it -- you vote in jail, you vote on the streets, you vote overseas, you have citizenship you get the vote regardless of
anything else) and make election day a bloody holiday already. On top of just mailing everyone we can reach a mail-in, postage paid, ballot. Etc., etc.
