“What would they impeach him for?”
He stole the election from Hillary. It was her turn, and Trump is a big doody-head. At least that is my interpretation of their bleating.
I really fear how they will behave next time a Republican gets elected following a Democrat President. They were bad in 2000, but in 2016 they were magnitudes worse. I suspect they will be willing to outright murder and ignite the Civil War.
