The House and Senate GOP are afraid of his voter base and act accordingly in lock step and 33 percent of all voters still gives him greater than 60 percent likely GOP voter approval. So this boils down to House should have expanded from 435 and Senate was a mistake unless one thinks land area of happenstance state lines is good proxy for decision making power (since competent and determined minority in senate can just stop things from happening also as opposed to number of votes of entire nation for presidential election)
