How Democracies Die

by Steven Levitsky

An essential test for democracies is not whether such figures emerge but whether political leaders, and especially political parties, work to prevent them from gaining power in the first place—by keeping them off mainstream party tickets, refusing to endorse or align with them, and when necessary, making common cause with rivals in support of democratic candidates. Isolating popular extremists requires political courage. But when fear, opportunism, or miscalculation leads established parties to bring extremists into the mainstream, democracy is imperiled.

Building on Linz’s work, we have developed a set of four behavioral warning signs that can help us know an authoritarian when we see one. We should worry when a politician 1) rejects, in words or action, the democratic rules of the game, 2) denies the legitimacy of opponents, 3) tolerates or encourages violence, or 4) indicates a willingness to curtail the civil liberties of opponents, including the media. Table 1 shows how to assess politicians in terms of these four factors.

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.
