Another certainty is that Pelosi, with a case prepared by major players in the lib community, will commence impeachment proceedings at the most opportune time.
No need for the Dems to impeach with the Mueller Coup being given a bipartisan veneer of respectability by Marco Amnestio and the rest of the GOPe. They’ll only impeach Trump if he fires Mueller.
That assumes Mueller is bullet-proof - I think he is out of the picture in the next 6 months. In either event, we know the dems increasingly tend to pile on.
