A central question of Mark Tribe's artistic practice asks how media and technology have shaped the way politics are performed. The Port Huron Project (2006-2009) is a series of reenactments of protest speeches from the New Left movements of the Vietnam era and includes speeches by Stokely Carmichael (1967), Cesar Chavez (1971), Angela Davis (1969), Coretta Scott King (1968), Paul Potter (1965) and Howard Zinn (1971).

Each speech took place at the site of the original event and was delivered by an actor or performance artist to an audience of invited guests and passersby. Videos of these performances have been screened on campuses, exhibited in art spaces and distributed online as open-source media.
