In reality all that's going to do is move the Overton window to the left. Game theory and history tells us you'll end up with a more left-wing Democratic party that appeals to 40% of the population; a centrist Labour party that appeals to 40% of the population; and an American Freedom party that appeals to 10% of the population. And the American Freedom party will have like five Congressmen and a Senator, and that will be the full extent of their power; and they'll dissolve a decade later when everyone realizes they can't actually get anything done.
Perfect.
