Impeachment: President Trump told House Republicans at a party retreat that they must retain control of the chamber in the midterm elections, saying he expected to face a third impeachment if Democrats retake the majority. “They’ll find a reason to impeach me,” Mr. Trump said. “I’ll get impeached.” He warned about the history of midterms going against the party that holds the White House and said trumpeting his administration’s policies was a “road map to victory.”
I’d expect Trump’s 3rd and 4th impeachments to go like the first two, i.e. he stays in office. Also, it would be very hard to find charges against Vance as VP.
If Trump did somehow get removed, Vance would take over as President, and it would take him a while to do enough bad stuff to get impeached and removed. And by then, he would likely have gotten his own VP confirmed, who would then inherit the office from Vance. So all this stuff about removing Trump and making things good again is wishful thinking.
