"What kinds of candidates tend to test positive on a litmus test for authoritarianism? Very often, populist outsiders do. Populists are antiestablishment politicians—figures who, claiming to represent the voice of “the people,” wage war on what they depict as a corrupt and conspiratorial elite. Populists tend to deny the legitimacy of established parties, attacking them as undemocratic and even unpatriotic. They tell voters that the existing system is not really a democracy but instead has been hijacked, corrupted, or rigged by the elite. And they promise to bury that elite and return power to “the people.” This discourse should be taken seriously. When populists win elections, they often assault democratic institutions."
