Trump skates on this and Nancy (who held off the left as long as she could) knows that 2020 is going down the tubes. This act will only fire up the Trump supporters. It's like Don Quixote fighting a windmill.
And IF (big IF) the dems do take the WH, can you imagine the unfettered attack Trump will go on with the knowledge he now has of the swamp and it's workings? OMG, it will be a train wreck.
