Not only that, but it shows that a lot of people who voted for Trump in '16 are having buyer's remorse.
They understand now that they allowed themselves to be duped into helping elect the most unqualified and unfit for office clown in the history of this country and that the only way to rectify their mistake and hopefully reign him in, is by giving power back to his opposition.
They also realize that the Republicans will do nothing but bow before him and kiss his ring.
Among other things.
If that kind of buyer's remorse could exist in a small, highly pro-Trump district, imagine what can be out there nationally.
