Folks,
The U.S. is a Republic. As such, Ms. Cheney is the elected Congressman from Wyoming. In fact, the only one. As their representative, she needs to listen to her constituent's wishes and needs. But being a Republic, she can vote as she wishes.
And the voters of Wyoming can throw the bum out, if they wish. It is becoming increasingly apparent that is the wish of the good people of Wyoming.
May she get her ass stomped in a humiliating defeat, so that she may enjoy the air of Northern Virginia, which is where she lives, anyway.
