Liberals and Never Trump conservatives regularly castigate congressional Republicans for their cowardice. And certainly, some percentage of GOP politicians are abetting Trump’s malfeasance for craven, careerist reasons. But it’s the ones who are doing so out of moral conviction who should truly concern us. Understanding pro-Trump conservatives as a pack of spineless opportunists putting short-term political expediency above their highest ideals is almost certainly too optimistic. In a hyperpolarized political system — and in the face of demographic and ideological headwinds — many conservatives simply see little reason to value the maintenance of democratic norms above the preservation of their movement’s power.
