Here's a novel idea. Allow voting for a two-week window or thereabout. Require in-person voting with valid identification. Close the polls at 5 p.m. local time on the first Tuesday after the first Monday in November. Count the votes immediately thereafter.

COVID-19 has changed everything as far as WFH, etc. There's an exodus coming, this is just the beginning. CA residents are already voting with their feet to places like AZ, CO, TX, NV.
