What is their endgame? There is zero chance the Senate will convict. Would the Dem's really impeach and let someone like Adam Schiff be brought before the Senate Intel Committee where he will be under oath?. Remember that Schiff had the whistleblower report nearly a month before it was announced by the IGIC. First he denied the fact that there was contact, then it leaked out. How long do you think it will take Sen. Graham to call firs the whistleblower, then Schiff's staff then Schiff to testify? If forced to answer questions, how long do you think it will take to link other big names to the scam behind how the whistleblower was brought forward?
Do you really think Schiff wants to be called in front of the Senate where he would have ZERO power?
There endgame is to do their jobs. They cant control what the Senate does, but if they feel impeachment is what needs to happen they should still do their jobs. Again we will wait and see, but I almost guarantee you are going to be wrong.
