Randall Balmer, a historian of American religion, spent his high school years in Des Moines, Iowa. His father was a staunch Republican and pastor of one of the largest evangelical churches in the state—but he was resolutely apolitical in the pulpit. Beginning in the late 1970s, however, the issue of abortion galvanized evangelical political activism in Iowa, and the state became a harbinger of movements on the religious right. Evangelicals formed megachurches and homeschooling became popular. Iowa's long tradition of progressivism has been blunted, as is evident in the 2010 recall of three Iowa Supreme Court justices who ruled in favor of same-sex marriage (Religion Dispatches, December 31).
