The University of Texas at San Antonio will host a presidential debate Tuesday evening. But not one involving the two main candidates or their surrogates. Members of UTSA’s Students for Justice in Palestine invited politicians from a variety of third parties to discuss issues including the Israel-Palestine conflict, immigration, mass incarceration, climate change, student debt and healthcare. The Middle East conflict “will receive focussed attention,” according to details shared by organizers. Those taking the stage will include Libertarian Party presidential candidate Chase Oliver, Texas Railroad Commissioner Green Party candidate Eddie Espinoza and Nicolette Ardiente, president of the Bexar County Young Democrats. Victoria Ramirez, Texas campaign coordinator for the Party for Socialism and Liberation, also will attend.
