This chapter tests another observable implication of the protest state theory; namely that where protest has normalized as an everyday form of political voice, political elites actively mobilize demonstrators in pursuit of their goals. In other words, rather than serving only as a spontaneous political expression of the masses, protest is often orchestrated and managed by formal political organizations. I first investigate how linkages to political organizations fuel contentious behavior in protest states like Argentina and Bolivia, but are more strongly associated with conventional participation in strongly institutionalized contexts like Chile and Uruguay. Then, utilizing a unique battery of questions from the AmericasBarometer national surveys of Argentina and Bolivia, I also test the hypothesis that clientelism can motivate protest participation in a context where protest has normalized as a standard form of political voice.
