It’s been more than a half-century since Joe Biden was first elected to public office.

Even for a guy who finished near the bottom of his law school class, you figure that’d be long enough for Biden to understand what “semi-automatic weapons” are.

But no.

Friday’s CNN This Morning led with talk of the president “taking action” on guns in the wake of recent mass shootings. Don Lemon said Biden was “railing against access to assault weapons in this country.” Then Biden denounced guns as he vacationed in Nantucket.
