Were any of these responsible for any future trouble in the United States? If so, which one(s) and how were they responsible?

At a frenetic and freewheeling rally in Macon, Ga., in mid-October, with less than three weeks to go before the election, President Trump turned introspective. He reflected on what sets him apart from every other president in American history: his refusal to be presidential.

“I always said, it’s much easier to be ‘presidential’ than to do what I do. ... I’m more presidential if I wanted to be, but I got to get things done,” he said. “I don’t have enough time. ... I can be more presidential than any president in our history — with the possible exception of Abraham Lincoln when he wore the hat. That was tough to beat.”

What does it mean to be presidential? Article II of the Constitution describes the office in just a handful of paragraphs. To a remarkable extent, the presidency is shaped by unwritten traditions and expectations that historians and political scientists call “norms” — what political scientists Steven Levitsky and Daniel Ziblatt call the “soft guardrails” of American democracy.

Violating presidential norms doesn’t equate to breaking the law. Can Trump steer taxpayer money to his businesses? Can he call for the investigation of his political rivals? Can he fire people in oversight positions and replace them with loyalists? Yes — technically — he can. But should he?

One of the things Trump has forced presidential scholars to realize “is the extent to which shamelessness in a president is really empowering,” says Jack Goldsmith, a former Justice Department official in the George W. Bush administration who teaches at Harvard Law School. The current presidency also reveals “the extent to which the whole system before Trump was built on a basic assumption about a range of reasonableness among presidents, a range of willingness to play within the system, a range of at least a modicum of understanding of political and normative constraints.”

Goldsmith and others argue that Trump’s steamrolling of norms could do lasting damage to both the stature of the presidency and the institutions of democracy if reforms aren’t devised to bolster the fragile tissue of these shared understandings.
