Now, for the first time in modern history, a major-party candidate rejects both sides of that equation. If he loses, Donald Trump says, it will be due to cheating that makes the result illegitimate. If he wins, he will imprison his defeated opponent.
Many Americans may not have given much thought to what a breathtaking departure this represents, because until now we have had the luxury of never having to think about such things. We have been able to take for granted the quadrennial peaceful transition of power. We watch from a distance when political parties in one foreign country or another take up arms after losing an election. We look, as at something that could never happen here, when a foreign leader sends an opponent to jail or into exile. This can happen in Zimbabwe, we think, or Russia, or Cambodia, but not here. Not in the United States.
