MICHAEL BARONE: Trump’s Inauguration Is Not Without Precedent.

Jackson was regarded as a wild man, impetuous, unfit for the presidency, by Jefferson, Madison and Monroe. Each surely preferred the scholarly, internationally experienced Adams.

Similarly, all of Trump’s three eight-year predecessors — Clinton, Bush, Obama — take a similar view of Trump, though all three accepted invitations to his inauguration. But many other presidents — Lincoln, both Roosevelts, plus some duds — had no support from living predecessors. Trump is not quite so unprecedented as many of those unversed in history think.

Nope.
