I posted this over on Fascist Book ... some research on the mail in ballot deadlines:
270 ELECTORAL VOTES TO WIN.
Ballots requested and outstanding need to be counted and accounted for. Late ballots should not count, you have plenty of time to get the ballot and get it in. Here locally you can personally take a mail in ballot to the court house and hand to clerk or a secure drop box inside of courthouse. There is still 6 or so weeks and no reason people cannot plan on getting their vote there in time, or to vote in person like V.P. Biden managed to do.
Many states have mail in ballots for voting on a regular basis. A Trump backed Californian congressional special election was heavily mail in and the Republican won. I think it was Los Angeles. So it is not new, what is new is state like Nevada trying to do unrequested ballot drops, trying to allow ballot harvesting. Regular mail in is you request the ballot yourself to verified home address using verified state ID (driver's license where you proved address and citizenship with a birth certificate). That is just like absentee just it allows by request for any reason and is common and IMO not too different than in person where often I did not have to present my ID, only gave my name and address.
STATES THAT REQUIRE BALLOTS ARRIVE BY ELECTION DAY. Thirty states and Trump won 21 of those last time (Maine was split).
Maine (3 but- split delegates not sure if Trump had 1 or 2 in 2016 – looks like 2)
Nebraska (split possible but Trump won all 5?)
South Carolina 9
South Dakota 3
(190 if Trump only had 1 from Maine 191 if 2 I think 2 is correct though)…
New Hampshire 4
New Mexico 5
Rhode Island 4
BALLOTS postmarked either day before or day of election that can arrive after election day (but if outstanding less than differential these states can be called election night as well).
Ballots mailed must arrive the day after election:
Texas 38 (191+38 is 229 Trump if all same per above)
Ballots arrive by 3 days after
North Carolina 15 (Trump won all these 229+16+6+15 = 266)
Washington (state) 12
Iowa 6 (266+6=272 electoral votes and latest this should take, if picks up some prior blue states and clear victories can easily be called on election night)
West Virginia 5
New Jersey 14
New York 29
North Dakota post mark 1 day before election, no specific arrival.
longest other states would be California post mark by election day, receive in seventeen days … 55 and Nevada postmarked on or before election day, no arrival date given 6 vote Trump won electoral without those two states prior CA and NV so even if they try to inflate popular weeks after, doesn't matter if he has the electoral college won. That is the Constitution. If people don't like it they need to change that, but it is there for a reason. Glad we have it so that the entire county is not literally on fire.
