OK, so explain to us what the Republicans can do to avoid being sidelined in this faux impeachment investigation.
Easy question. McConnell should have called Pelosi and told her any witness that testifies before this Kangaroo court in the House will also be testifying before the GOP controlled Senate ASAP. Starting with the IC IG who is obviously a coupist.
Instead, McConnell has given the House Dem and Deep State coupists weeks to gaslight their message, destroy evidence and change tack as needed. I can only conclude that is because Do-Nothing McConnell does not care one bit if POTUS is impeached.
Maybe you are right...or not. There is no way to know for sure until it plays out.
Right now I believe all of them in the Congress (maybe 1 or 2 exceptions) are azzholes of the highest order and taht includes both sides.
