[mdlbear]

By way of rydra_wong posting in thisfinecrew, here's FiveThirtyEight: How To Vote In The 2020 Election: A state-by-state guide to voting in the age of COVID-19.

Please note that this is not about who to vote for -- if that's not blindingly obvious at this point please get out from under that rock. It's about the process of voting; in particular the procedures and requirements for voting by mail. Hopefully it will be kept up to date.
