You can imagine why this would be. Leading members of Congress might resist invoking the 25th Amendment, which would of course be described by Trump’s supporters as a “Cabinet coup.” The mob — not the literal, physical street mob, but the online mob that has replaced it — would seek revenge. There may not be any presidential goons, but any senior official who signs his or her name to a call for impeachment or removal will certainly be subjected to waves of hatred on social media, starting with a denunciation from the president. Recriminations will follow on Fox News, along with a smear campaign, a doxing campaign, attacks on the target’s family and perhaps worse. It is possible we have underestimated the degree to which our political culture has already become more authoritarian.
