If this, republican majority impeached him, then the senate would definitely convict. In that case Trump is no longer the president.
The past two times dems held the house, but not the senate, so Republicans in the senate prevented a conviction.
Impeachment means there is evidence of misconduct (at a significant level). Senate conviction means you’re out as president.
If we get to the point where the senate convicts him, I think it’s game over. That means that republican party has finally turned on him (meaning they think the public has too).
US is sliding towards authoritarianism, but having the whole country against you is still not something he can overcome.
