Well, the Kavanaugh thing didn’t really seem to hurt them, did it? They are in charge in the House, they got their toe-hold. At least it didn’t hurt them beyond their ability to openly commit fraud to make up for it.
They could face the same fate in the house, if they push impeachment too far.
With voter fraud working for them so far, they may not think it will hurt them in 2020.
I'm just saying it is a possibility.
