If PA flips that's 20 electoral college votes so it is down to 286 for Biden. So 17 more and he's fucked.
The Wisconsin recount is apparently going well for the GOP with loads of illegal ballots being tossed. That's 10 electoral votes
The Arizona recount is close. That's 11 electoral votes
Michigan is 16 votes and there's vast amounts of evidence of fraud.
Trump is going to GA, which is 16. It's absolutely critical that the GOP wins the Senate run-offs and there's loads of evidence of fuckery.
From polling, we know an overwhelming majority of Trump voters think the election was rigged. All they need to do is to put pressure on the Republican leadership in the state legislature and it will flip.
So what we've got is a weird sort of election where the electorate is the Republican leadership in the state legislatures who know an overwhelming majority of their supporters want them to do something. They also know if the Democrats rig this election they could easily rig the state legislature elections.
They don't even need to send Trump electors. They could just decline to send any electors or dispute that the Biden electors were chosen by a fair election and if enough of them do it it will cause a contingent election.
Incidentally, I've thought of an ingenious exit ramp from chaos. GOP state legislatures send Trump electors or refuse to certify leading to a contingent election in which Trump wins. Now Trump says that there is evidence of massive fraud but that many Americans do not accept that Trump should have been re-elected by this mechanism. So he steps down. Pence takes over as POTUS and pardons essentially everyone who could be convicted of rigging or made-up political crimes. Trump says he'll work on starting an alternative to the media which tried to cover up the coup.
Incidentally, look at this

If Trump resigns before the end of his current term and Pence pardons him he'd be free to run in 2024.
