This whole thing will be another Mueller report and go nowhere unless they get some real evidence. A reconstituted transcript and a complaint fromsomeone who was not present is not evidence. There is no explicit quid pro quo. You don't need that to charge, but you'll have a tough time removing him without one. He isn't above the law, but he is also not above it's protections.
This is only a slam dunk to those who hate him so much that they are deluded by their hate. Maybe his intent was a quid pro quo, but you'd have to prove that by legal standards not the court of public opinion, which has no standards of evidence. You may as well that the Dems are doing this all for political purposes - it may be true, but can you prove it?
They have nothing that will stand up in court. Impeach away, that's just an accusation. The Senate will take it up because they have to, and it will die there without ever getting to 67.
