I doubt Trump gets removed from office following impeached. He will either quit (unlikely, but possible if an immunity deal is cut), be voted out or win re-election.
If Trump quits, sure Pence is Pres. He's unelectable in a National General (the charism of a Datsun B210) so let him keep the seat warm. He'll be investigated to death to, as he was Paulie Walnuts boy and has some email issues of his own...
You believe " Mary Poppins " is a documentary don't you...........
