Trump slowed up the us mail system and the Supreme Court ruled any votes not received tomorrow won’t count?
Supreme Court ruled in one state that votes couldn’t be received after Election Day because that state’s laws did not allow it. Other state laws, such as Pennsylvania, do allow it.
The concern is that the SCOTUS will decide that those laws, allowing votes collected after Election Day, will be deemed unconstitutional. I think that is unlikely. Also, the number of votes received after Election Day are very low and a LOT of them are from overseas military.
What is likely to happen is that the Trump Court will rule that state legislatures, not state courts, have the final authority to determine the validity of ballots:
“…an election dispute in states like Pennsylvania and Michigan, which have state legislatures controlled by Republicans but Democratic governors, could lead to different branches certifying competing slates of electors.”
Justice Kavanaugh's opinion comes as President Trump has complained about the length it could take to count all mail-in ballots.

And those Republican-controlled state legislatures will no doubt decide the matter in Trump’s favor.
