Many in the Republican establishment regard Donald Trump's presidency as something merely to be endured, a temporary disruption that too shall pass, after which the party's long-standing orthodoxy can reign once more. Such thinking is misguided, both positively and normatively. While President Trump may himself be an aberration, his victory improbable and overdetermined, the economic challenges and political fractures that he helped expose were already features of the American landscape and are going nowhere. The GOP (and the Democratic party) must adapt to and address them.
