Impeachment? Not going to happen and here is why:

It's really quite simple,  no evidence,  no impeachment trial   . . . . .    period.  The evidence has to be unique to this presidency not to mention "hard evidence" of the crimes charged to the President.   And the evidence has to have widespread,  bi-partisan appeal.  Trump will not be found "guilty" of high crimes and misdemeanors without bi-partisan support.  Ain't going to happen.  

There is nothing worse for the Dems,  in an election year,  than to trump up an "impeachment" effort that, in the end,  fails in the above mentioned three categories.  As things stand,  now,  this is the plight of the "prosecution."   

You might ask,  "What about treason or collusion,  or fiscal malfeasance?"  Answer:  During the trial,  these cannot be determined as the result of debate.  The charge of "high crimes" must be supported by an evidence package that is considered a "smoking gun" establishing undeniable guilt that is (a) obvious to all  and (b)  and above partisan bickering . . . . .   alla Richard Nixon.  

Bill Clinton suffered through a trial that produced a misdemeanor  at best,  and, nothing more.  It was a massive waste of time,  and Clinton may have won re-election because of the failure.    

So,  as things stand today,  unless Mueller cites hard evidence of high crimes,  there will be no impeachment,  and,  Trump will use this reality to win re-election.  Take it to the bank.
