Impeachment Lottery?

[Anomalocaris]

Nixon was a clear exception; he would not have resigned otherwise.

Nixon was never impeached.  He resigned before the vote to impeach took place.

Prediction:  The situation with Trump will be slightly different.  Over the next several months, there will be a slow but inexorable shift among Senate Republicans, and the 67 majority will be reached. He will be successfully impeached by the House, but will resign before the Senate trial.  He will leave office on or before 30 April 2020.

There won’t be any inexorable shift unless there is first a critical mass of Republican who already shifted.  There won’t be any critical mass of Republicans who already shift unless there is first a inexorable shift amongst republicans.   Shift for most republicans will be seen as the last option and really no option at all, because successful impeachment and trial will vastly discredit the right wing media and thereby deprive each one of them of the oxygen that sustains a most national Republican political careers.  

Republicans will gamble instead on the successful theft of the next election, after which they can confidently exhibit their fealty to trumpism in the senate.
