I was considering the apparent polling error and the inevitable handwringing that's going to happen and then I had a realisation - there could be a "DeJoy effect" - somebody should track mail-in ballots that arrive too late to be counted but were postmarked reasonably early so we can see if Trump stole Florida and North Carolina and how close he came to stealing the election. Also, once Biden is in office, postal workers should be encouraged to come forward to talk about tactics put in place to slow down mail-in ballots.
