On the mail-in voting issue:
It is wrong to require people to go through the normal voting procedures given the ramifications of Covid-19. Depending on the individuals health, this is risking their life to vote. I have a friend who is 92 and is by all appearances, and talking to him, in great health; but he certainly looks at Covid 19 as something not to play Russian Roulette with.
However, if the concern is so great over fraud with mail-in ballots, it seems like some variation of dedicated ballot drop boxes at the same schools/churches run similar to the way the drive-through/walk-through Covid-19 testing is done. A group of people more familiar could work it out; but, for example, I might imagine a sheet of plastic with a hole for passing ID back and forth (or the owner could display it through the hole while the poll worked verified it) and then handing the completed ballot to the worker and the voter watches it go through scanner and put into secure box for paper backup. (I assume they use scanners, but however it is done, this does not seem hard if the current administration wanted to do it - you could have the same checks currently used indoors being done outside.
A little more interesting, it seems like ATM's could easily be adapted to record person holding up ID, posing for face pic, and deposit ballot. Probably couldn't happen this year, but I could see it as the future of voting!
