William Sweeney, Chad Vickrey, and Katherine Ellena WaPo oped:

Is the U.S. presidential election vulnerable to manipulation by a losing candidate? Could the integrity of our electoral process be successfully challenged? Unfortunately, the answer to these questions is yes.

The International Foundation for Electoral Systems (IFES) has supported the integrity of political and electoral processes in more than 145 countries for nearly 30 years. We have developed a rigorous methodology to analyze vulnerabilities throughout the electoral process, drawing on international standards and commitments that stem from fundamental rights guaranteed in the Universal Declaration of Human Rights, International Covenant on Civil and Political Rights, and other international accords. We have applied this in multiple countries to fortify elections against malpractice, fraud and systemic manipulation.

From this global perspective and experience, we have increasingly seen the credibility of elections — and, in some cases, the stability of the election environment — hinge on the ability of electoral institutions, and in particular the election dispute resolution process, to withstand increasingly sophisticated political manipulation.
