Abstract

ABSTRACT Most critics of the U.S.-Mexico border wall assume that it represents the xenophobic nationalism typical of right populism. However, the populist message of exclusion is directed not at migrants but at the liberal democrats who compose the traditional mainstream of politics. The wall’s populist message is meant to expose a contradiction: liberal democrats do not know how to reconcile borders with their official commitment to universal inclusion. Right populism and left populism, too exploit this contradiction. Liberal democracy could effectively respond to the populist challenge, however, by using the wall’s symbolic connection to geography and the environment.
