Unprecedented may be the most overused word in political discourse, but it applies to the post-presidency of Donald J. Trump.

Many former presidents maintained a public profile after leaving the White House, but none dominated his party and held onto the loyalty of his base despite being embroiled in so many allegations of corruption as Trump.
