Trump or Hillary elected president --- What then?

If elected president, Hillary’s criminal record would haunt her throughout 
her term in office, leading to the possibility of an impeachment. 
The presidency would become totally dysfunctional from the very outset, 
which her corporate sponsors including the defense contractors and 
Wall Street would prefer to avoid.

If Trump is elected president, there will also be attempts to unseat him,

calling for his impeachment.

If both candidates are dysfunctional. Is there a Plan B? 

Prove that
