In the third and last presidential debate Wednesday night, Donald Trump again refused to say whether he would concede to Hillary Clinton if he was the loser of the Nov. 8 election.
Americans must now contend with a candidate who casts doubts on the democratic process before the votes have been counted, and who suggests that the election is rigged, without offering any evidence to back up his claim.
This is unprecedented. By contrast, consider the behavior of past presidential candidates who lost elections — and who actually had reason to complain about the outcome, if not contest it.
Their example tells us much about the conventions and expectations that, until now, have ensured the stability of the U.S. political system.
Take, for example, Andrew Jackson. He had genuine grounds for believing that the outcome had been rigged and the democratic process subverted when he first ran for president in 1824. And yet Jackson, a man who typically settled disputes with dueling pistols, nonetheless graciously stepped aside when it became clear that protest would damage the nation's political institutions.
The election of 1824 featured no less than four candidates: the New Englander and former secretary of state John Quincy Adams; Henry Clay of Kentucky; Secretary of the Treasury William Crawford from Georgia; and Jackson, the war hero.
With the possible exception of Jackson, these candidates had regional followings. On Election Day, Jackson decisively had the broadest and biggest level of support throughout the country, garnering 41.4 percent of the total vote, with Adams far behind in second place, at 30.9 percent. The other two candidates picked up only modest support. Jackson also accumulated the most electoral votes, 99, compared with 84 for Adams.
But Jackson had not won a majority of the electoral vote, only a plurality. According to the 12th Amendment to the Constitution, that meant the election would be decided in the House of Representatives. At this point, the politicking and scheming began, despite the fact that Jackson was obviously the "people's choice," as a growing number of newspapers dubbed him.
