I don't disagree that many in the Republican party and MAGA movement would love for this to be the result in the coming months. However, conviction in the Senate on an impeachment requires a 2/3 majority vote. There is no chance the GOP attains that level of majority in either house of Congress this November.

The Rules on how a Speaker is elected by the House are vague enough that yes, they can elect a Speaker that is not a member of Congress, like Trump, with a simple majority vote. I don't see the entirety of House Republicans choosing to go down that path. McCarthy would most likely become Speaker. There are some crazies who might go ahead and vote for Trump or someone like MTG even. If they do, they might split the Republican vote enough to kill their own plans and potentially end up with Pelosi back in as Speaker.

None of that diminishes the need to vote this November for Democrat candidates to avoid further disaster. I'm just saying that your vision is a long shot at best.
