Ernst out, Hinson in; new Congressional candidates; Democratic town halls

Laura Belin and George A. Clark (filling in for Spencer Dirks) dug into Iowa's latest political reshuffle: Joni Ernst's exit and Ashley Hinson's Senate campaign launch, Hinson's competition for the GOP nomination, and the Republicans lining up to run for Hinson's seat in Congress. Other topics covered: another Democrat running for Senate, new endorsements for Josh Turek, another Republican running in the fourth Congressional district, town halls held by Rob Sand, Julie Stauch, and Sarah Trone Garriott, a Zach Nunn "community forum" that wasn't, and the state of Iowa's new law enforcement agreement with the Meskwaki Nation.
