The Cook Political Report has revised five House races in favor of Democrats, particularly in the Midwest. Two Iowa contests are now toss-ups as Democrats challenge Republican incumbents Mariannette Miller-Meeks and Zach Nunn. Additionally, races for Democratic incumbents in Illinois and Indiana have been upgraded to likely Democratic wins. Democrats require a net gain of four seats for a House majority this fall, amid a forecast suggesting a mixed outlook for the GOP.
