If Alabama voters on Tuesday elect Roy Moore to the Senate, the Donald Trump-diseased party once known as the Republicans may as well call themselves Roypublicans.

There will be no way to shake the stench of this homophobic, Islamophobic, sexist, racist apologist and accused pedophile. He is them, and they are him. Any pretense of tolerance and egalitarianism, already damaged by a Republican history of words and deeds, will be completely obliterated.

There will be no way to simply say that Moore is the abominable outgrowth of Alabama voters’ anger.

Moore has been fully endorsed by the Republican “president” of the United States, the leader of his party, and is now fully supported by the Republican National Committee. Last week, R.N.C. Chairwoman Ronna McDaniel told CNN: “The president has said we want to keep this seat Republican. The R.N.C. is the political arm of the White House, and we want to support the president’s agenda.”

The pre-Trump Republican Party is dead; The zombie Trump party now lives in its stead, devoid of principle, feasting on fear and rage, foreign to moral framing.
