Hard to tell yet. But Pence never was a Trump insider, so I give him the benefit of the doubt.
However, the proximal excuse for Flynn leaving was lying to Pence, so maybe???
If Pence is not an insider, he can distance himself from the Trump shit show. If Pence hasn't dirtied himself in the Trump pig pen, Trump has nothing on Pence and can't get ride of Pence. So Pence can just go back to the Naval Observatory and invite GOP members of Congress over for dinner. Pence can just stand to the side and wait.
If Pence is dirty, he has to keep the SS Trump afloat.
Watch what Pence does or doesn't do for clues.
