I've been wondering about that... Like what would Pence do with Bannon? Would he turf him and the white nationalists? What about Devos? Tillerson? Flynn? Sessions? Pruitt?
Carson 
?
I'm sure he would keep some of them
But if he replaced any of them, they would have to be with someone at least marginally better. Wouldn't they?
Pence is a horrible, horrible person. He is disgusting. But he still might be better than Trump. It feels like if Pence was POTUS there would be an almost zero chance of no more democratic free elections. With Trump the chance seems non-zero. Like uncomfortably above zero. It's just over a week into his presidency and things are scary as fuck.
