Raskin has a point when he charges that Trump’s ongoing “bizarre litany of events and outbursts” has raised legitimate concerns about his temperament and stability. But the 25th Amendment wasn’t designed for ejecting “merely” erratic or untrustworthy presidents. Introduced in the wake of the Kennedy assassination, it aimed at situations of total disability, whether temporary or permanent. The worry with Trump isn’t that he’s “unable to discharge” the powers of his office—it’s that he’s reckless and immature enough to do enormous damage while he does so.

We already have a standing body empowered to make an initial ruling on that sort of presidential fitness: the U.S. House of Representatives, to which the Constitution grants “the sole Power of Impeachment.” Contrary to conventional wisdom, that remedy isn’t limited to cases of corruption or abuse of official power. In its survey of the “Constitutional Grounds for Presidential Impeachment,” the Nixon-era House Judiciary Committee identified a third category of impeachable offense: “behaving in a manner grossly incompatible with the proper function and purpose of the office.”
