Eric Bjornlund for Foreign Policy:

As the co-founder and president of Democracy International, I now see the United States exhibiting many of the same kinds of problems with elections that we in the international election monitoring community have long criticized in countries where democracy is less established. In genuine, established democracies, political competitors generally do not attack the rules or the fairness of the process, accuse the opposing candidate or the election authorities of cheating, intimidate voters, or threaten them with violence. In less than fully democratic countries, on the other hand, complaints about fraud and fairness are routine, and violence—or the threat of it—is often involved. This tends to undermine public confidence in the elections and in democracy itself.

In the struggling democracies and autocracies where I have observed elections, much of the argument is about the integrity of the rules and process. Losing candidates routinely attack the fairness of the electoral process, whether or not they have a basis for their attacks. In fact, you can tell that a country is not (or not yet) a successful democracy when the losers of its elections blame fraud for their loss and attack the legitimacy of the process.
