Rob Sand will rally a crowd for the first time as the official Democratic nominee for Iowa governor on Sunday. The race between Sand and Republican Zach Lahn is expected to be highly competitive. Both candidates focus on issues like a struggling agricultural economy and a rising cancer crisis. Kentucky Gov. Andy Beshear supports Sand, believing he can flip the seat by prioritizing people over party. Sand, who dislikes partisanship, aims for balanced government in Iowa. Beshear, a potential 2028 presidential candidate, will campaign with Sand and other Democratic candidates in Iowa.
