One possible but highly unlikely, path:
2022 elections see a shift in the House so that the GOP is in control. GOP House members elect Trump as speaker (no, the speaker need not be a member of the House). House opens investigations into Biden and Harris that leads to articles of impeachment being filed.
[this is where it becomes next to impossible]
Both Biden and Harris are impached, Trump becomes President due to the Presidential succession.
That scenario has a LOT of appeal to me!
But Sloe Joe and The Hoe HAVE to be impeached in the House and Convicted in the Senate!
