While Deputy Attorney General Rod Rosenstein is surely disheartened to have had five articles of impeachment filed against him by a clutch of congressional Republicans on Wednesday evening, he should not take the move personally.

Although Representatives Mark Meadows of North Carolina and Jim Jordan of Ohio, the current and former chairmen of the conservative House Freedom Caucus who are leading this crusade, are running around Washington loudly accusing Mr. Rosenstein of high crimes and misdemeanors, their public relations assault is not actually about his refusing to turn over this or that document related to the Russia investigation. It’s not really even about the lawmakers’ loathing of the broader investigation, though certainly President Trump’s congressional lackeys — Mr. Meadows and Mr. Jordan most definitely included — are increasingly desperate to derail it.

For Freedom Caucus leaders, this impeachment resolution is about something at once much broader and far pettier: the need to make a huge, disruptive, polarizing political stink just as members head home for the long hot August recess. Especially with a critical midterm election coming, it never hurts to have some extra well-marbled meat to throw the voters. And it is unlikely a coincidence that, less than 24 hours after filing, Mr. Jordan — who, lest anyone forget, is multiply accused of overlooking rampant sexual abuse while an assistant wrestling coach at Ohio State University — formally announced his candidacy for House speaker.

Not to make Mr. Rosenstein feel any less special, but this is the fourth year in a row that Freedom Caucusers have pulled a summer-break stunt so nakedly self-serving that it would be comic if it weren’t so odious in its quest to erode public faith in government and in democratic institutions more broadly. Indeed, for all those wondering how the Republican Party reached the point where Donald Trump could swallow it whole with his furious everything-is-awful-and-everyone-is-out-to-get-you brand of demagogy, look no further than the nihilists in the Freedom Caucus.
