"The crimes for which impeachment is the prescribed punishment are notoriously undefined. And that’s for a reason: Presidential powers are vast, and it’s impossible to design laws to cover every possible abuse of the office’s authority. House Democrats have calculated that an impeachment focused narrowly on the Ukraine scandal will make the strongest legal case against President Trump. But that’s not Trump’s only impeachable offense. A full accounting would include a wide array of dangerous and authoritarian acts — 82, to be precise. His violations fall into seven broad categories of potentially impeachable misconduct that should be weighed, if not by the House, then at least by history."
