Stanley noted that rather than being restricted purely to populists, appeals to "the people" had become "an unavoidable aspect of modern political practice", with elections and referendums predicated on the notion that "the people" decide the outcome. Thus, a critique of the ideational definition of populism is that it becomes too broad and can potentially apply to all political actors and movements. Responding to this critique, Mudde and Rovira Kaltwasser argued that the ideational definition did allow for a "non-populism" in the form of both elitism and pluralism.
