In my opinion impeachment for any of these people is highly unlikely to ever happen.

The impeachment process has to be conducted by possible "future candidates" for impeachment, all members of "the good old boys political alliance".

Just as in Nixons case they will all protect each other because "in my opinion"
most of them have done as bad or worse things. The worst that will happen is being allowed to resign, and retain full retirement benefits as if they never did a wrong thing.

"We the people believe", it's a sorry state of affairs that will never get better.
Most politicians can make even ambulance chasing attorneys look like good guys.
