I don't think Trump would accept being barred from running in 2024 if the impeachment vote is allowed to go through. This is his only move right now. The national guard is already in the capital.
Booting him off of Twitter and social media, was a plan to disrupt his ability to address the nation, and possible liability around not carrying his address should he win. As I think some TV stations will probably block the emergency address. Trump is also convinced he would win the in person ballot, should a military declare a new election.
Media speaks almost in one voice now, joined by big tech, the left will be controlling almost all the levers of power otherwise. So he has large support in the population to stop that
