A recent SUnday New York Times Magazine profiled the latest of these Rush spawn to swim out of a small pond into the national conversation, a chunky, 42-year-old college dropout named Steve Deace. Strategically based in Des Moines, Iowa, Mr. Deace is a potential kingmaker for the Iowa GOP caucuses. Republican presidential candidates have lined up to get on his radio show -- just about everyone but Mr. Establishment, Jeb Bush, whom Mr. Deace calls "America's Hispanic fertility czar." Mr. Deace has now given his formal blessing to Ted Cruz.
