Sure, maybe Chapter 43 of the Trump follies will be the one chapter where media hysteria isn’t disproportionate to the end result. It seems unlikely. If the Mar-a-Lago raid turns out to be a Mueller-like down payment on a Justice Department failure to find the Jan. 6 crimes that many Americans are lusting to see Mr. Trump prosecuted for, one collateral cost is Mr. Trump’s extreme delight at being returned to the center ring of the American political circus—and also the extreme delight of his codependents, Joe Biden and the Democrats.

Mr. Biden’s party has given America something to talk about (and talk about and talk about) besides inflation, crime, racial and gender panic, and Mr. Biden’s low approval ratings—none of which were working particularly well going into the midterm elections that are barely 2½ months away.

We shouldn’t underestimate the secret delight of Mr. Biden himself as he looks toward 2024. His best ticket back to the nomination despite his age, lousy polls and an unprepossessing record is Mr. Trump being the likely Republican nominee.

Mr. Biden has said as much himself several times and he means it. And nothing helps like the astonishing concatenation of DOJ-FBI inquiries bearing the public ceaselessly back to the battlements of yesteryear however much voters might wish to move on from the bizarre, technicolor fights of the Trump era.
