You are overlooking the WIFM factor. If the GOP believes Hillary will win, and this is the only way to prevent her from holding the Presidency...their goals will align with what is right and just.
You are kidding, right? Did I miss your sarcasm?
John Boehner: “Due to the multiple lies and obstruction of justice, we are having meetings to consider the possibility of beginning impeachment proceedings against Hillary Clinton.”
One 24 hour news cycle later....
John Boehner: “Oh, no, there was never any serious consideration of impeachment. That will not happen.”
