This week on Reign of Error, host Sarah Posner speaks with Texas Monthly senior writer Robert Downen about how long-standing anti-Muslim activism has moved from the fringes of right-wing politics to the center of Texas GOP campaigns. They examine the role of Christian nationalist figures, right-wing media, and national operatives in fueling the backlash—from curriculum battles in Texas schools to calls to designate Muslim organizations as terrorist groups. The conversation also explores how fears about Sharia and Muslim “invasion” are intertwined with broader Christian nationalist efforts to redefine the United States as a “Judeo-Christian nation,” reshaping policy debates not just in Texas but across the country.

Last week’s Texas Republican primaries were widely framed as a contest between an “establishment” Republican and a more extreme MAGA challenger. But when it came to Islamophobia, the differences between candidates were far less clear. Across races for Senate, attorney general, governor, and even railroad commissioner, Republican candidates competed to amplify anti-Muslim conspiracy theories—portraying Islam as a political ideology rather than a religion and warning of a supposed “Islamification” of Texas. The panic centers on claims about Sharia law and developments like the proposed EPIC City Muslim-centered community near Plano, which far-right activists have recast as evidence of a looming civilizational threat, despite Muslims making up only a small fraction of the state’s population.

Robert Downen is a senior writer at Texas Monthly who often focuses on the intersection of politics and religion. Before joining TM in 2025, he covered politics and extremism for The Texas Tribune, where his work on the influence of far-right megadonors and white supremacists on the Texas GOP won or placed for numerous national investigative awards. A native of the Chicago suburbs, Robert arrived in Houston the day before Hurricane Harvey, and soon after, he began leading the Houston Chronicle’s groundbreaking coverage of sexual abuse in the Southern Baptist Convention—coverage that led to historic reforms, new laws in Texas, and a Department of Justice investigation.
