@livinglava,
Interesting argument. Thanks.
I believe the prospect for Trump's impeachment by the Congress is about zero.
=> ~Seven Democrat Senators are already declared against impeachment. That and the Republican majority renders the achievement of the required 67 votes to impeach in 100 person chamber unachievable.
=> The required Trail in the Senate gives Republicans wide ranging powers to investigate related matters that may affect the President's defense. This poses serious risks for many Democrats relative to their many actions during the past three years sustaining fruitless continuous investigations of san elected President, starting before he even took office.
=> The constitution gives the President the responsibility to conduct our foreign relations and to investigate potential corruption without respect to the political proclivities of those suspected. To prove Trump's guilt in his phone conversation with the Ukrainian President (in a conversational topic started by him - and not Trump) the accusers will have also to prove Biden's innocence in his son's curious but lucrative relationship with the Burisma Petroleum company. That will drag in the younger Biden's Chinese ventures and many other issues involving the former VP. The result could well be destructive to the Democrat's prized Obama legacy as well as their current political prospects everywhere.
=> Finally proving either criminal intent by Trump or that an investigation into foreign corruption corruption was, in effect, a campaign contribution appears (to me at least) to be impossible.
As a related matter, Speaker Pelosi's decision to announce an impeachment inquiry (for which she has as yet taken no action to implement), strikes me as very curious for a seasoned politician who surely understands all of the above points. What was her real intent? Given that the chief effect so far has been the effective end of the Biden candidacy in the intense inquiry & public discussion of the strong odor of corruption in his past actions, it is at least plausible to conclude that she simply sacrificed the Biden candidacy to protect her party from more serious harm later.
