WASHINGTON — Lucky there’s no Saturday detention at the Capitol.

Republicans — and some Democrats — would certainly make like Mr. Vernon, the “Breakfast Club” disciplinarian, and lock down the irrepressible Alexandria Ocasio-Cortez. She’s only been in town a moment and has already, in this city of acronyms, become famous enough to supersede the shorthand for the Architect of the Capitol.

A.O.C. now simply signifies the congresswoman from the Bronx and Queens.

No longer content with Nancy Pelosi, the right craves a new she-devil. Republicans have mocked Ocasio-Cortez’s hardscrabble story, howled at her proposal to soak the rich with a 70 percent tax, scrutinized her clothes and booed her at Pelosi’s swearing-in. A.O.C. saucily tweeted back, “Don’t hate me cause you ain’t me, fellas.”

The frenzy reached new absurdity when a tweet popped up with a video of her with friends at Boston University doing a dance from “The Breakfast Club,” with this slam: “Here is America’s favorite commie know-it-all acting like the clueless nitwit she is.” Holy Footloose.

“It is unsurprising to me that Republicans would think having fun should be disqualifying or illegal,” she told The Hill.
