Conservatives must also let go of fantasies about saving the “good” Republicans, a list that is virtually nonexistent. (You can’t count Mitt Romney more than once.) The occasional furrowed brow—a specialty of the feckless Susan Collins of Maine—is not enough. The few, like Romney, who have dared grasp at moments of sanity have been pilloried by Trump and other Republicans. In any case, Romney is chained to the GOP caucus, a crew that includes the jabbering Louie Gohmert and calculating Elise Stefanik in the House, and the sniveling Ted Cruz and amoral Mitch McConnell in the Senate.

Would-be Madisonians among the Republicans warn that no party should have untrammeled access to the levers of power—and especially not the Democrats. Yes, they say, we understand that Trump must go, but if Joe Biden is allowed to run the executive branch without a Republican Senate, America will become a one-party state that sooner or later will fall under the boot of the dreaded Representative Alexandria Ocasio-Cortez. This faux constitutionalism is naked hypocrisy: I do not recall, during my days in the GOP, anyone on the right ever pleading that Americans should leave at least a few Democrats in office so that we Republicans would not go crazy and start force-feeding Ayn Rand or Friedrich Hayek to impressionable schoolchildren.

America needs two healthy political parties. So if the Republicans suffer a full-spectrum defeat in 2020, what comes next? At the least, a shattering loss should result in a wholesale purge of the Republican National Committee. Even donors who like what they got from Trump will not pour money into a losing proposition.
