Just because impeachment proceedings backfired on Republicans doesn't mean that it will

12. Trump convicted of multiple felonies will be very difficult to defend in Congress.

I do not forsee Trump functioning as President while his entire family and many in his administration are convicted and sent to prison. Nor while each political move he makes is contested as illegal and unconstitutional.
It may also come to pass that some of his strongest supporters in the Senate are themselves convicted. That's a circumstance to seriously consider.

This whole conspiracy is much larger than Trump alone. He is the distraction from it as much as the agent in place. The legal consequences of the Mueller investigation will probably take quite a while to unfold and prosecute. As we have seen so far the fraud charges in NY and the Emoluments cases elsewhere have lives of their own. The question of espionage and treason has been raised but remains largely unprosecuted. Money Laundering is one thing, withdrawing from the Nuclear Arms Treaty to enable selling nuclear power and weapons tools the Saudi Crown Prince is quite another.
