It doesn’t matter what they might or might not “consider”, if they impeach Trump them Vance becomes President, unless they do a twofer and impeach them both.
If they ever have the votes to impeach Trump, they would likely have the votes to impeach both of them. But, they may think it’s political suicide to do so, especially since then a (presumably Democratic) House Speaker would become President, and not by being elected, which would trigger all sorts of folks on the Reich Right




Nope, that is incorrect.

If a Presidential impeachment succeeds, that person immediately leaves office. The Constitution says that if the President were ever to leave office, the VP takes over. But if there is also no VP, what happens next depends on the Presidential Succession Act:

Which says that the Speaker of the House becomes Acting President.
Its still a matter of debate what exactly an “acting President” can do in this context. Does the House Speaker resign from Congress and move into the White House? That is the plainest reading of it all, after all.
