Impeachment would remedy Trump’s “high crimes and misdemeanors.” But impeachment would not remedy Trump’s unconstitutional presidency because it would leave in place his vice president, White House staff and Cabinet, as well as all the executive orders he issued and all the legislation he signed, and the official record of his presidency.
The only response to an unconstitutional presidency is to annul it. Annulment would repeal all of an unconstitutional president’s appointments and executive actions, and would eliminate the official record of the presidency.
Annulment would recognize that all such appointments, actions, and records were made without constitutional authority.
The Constitution does not specifically provide for annulment of an unconstitutional presidency. But read as a whole, the Constitution leads to the logical conclusion that annulment is the appropriate remedy for one.
After all, the Supreme Court declares legislation that doesn’t comport with the Constitution null and void, as if it had never been passed.
