The trouble with that, is McConnell has to get Trump to do it.
He won’t.
For one thing, the President is a coward. Notice how he never actually fires people face to face?
For another, he’s personally sensitive to this kind of charge. So he will feel that it reflects on him. Cuz it does.
Finally, Trump won’t want to blame a Republican capitulation on Democrats, cuz that would mean Ds won – and he lost.
Trump is going to blame the loss on Republicans who wouldn’t fight – so he didn’t lose, personally.
