If (D)'s go with impeachment, and the transcript isn't released until sometime after....it won't matter if the transcript is totally favorable to Trump.
nancy has already stated there doesn't need to be a Quid Pro Quo for impeachment, there only needs to be talk about a political opponent.
Once she says go, they will regardless. It will be their last ditch attempt to try and prevent Trump from getting re-elected and it will be a test of the nation to see where our future is heading.
Where are the high crimes and misdemeanors?
