The question will be whether or not enough college-educated White voters will seem satisfied with their Republican Congresspeople being, well, "not Trump." When Republican politicians are regularly denouncing Trump's outbursts and ideas publicly, it begs the question if that will be enough to satisfy these voters who usually leaned Republican but don't like Trump ... it remains to be seen in 2018, but it was enough in 2016.
Many people thought they were voting for a Republican Congress to counter a President Hillary Clinton. I could see them wanting the opposite to counter Trump in 2018.
