Iowa primary set for Tuesday
Tuesday in Iowa, Democratic voters will decide which of five candidates will take on Republican Gov. Kim Reynolds in the state's gubernatorial election in November. Reynolds is seeking her first full term as governor of the Hawkeye State. There are also races in the state's first and third congressional districts that are expected to be closely contested, as the incumbent Republicans face challenges from Democrats. Rachel Stassen-Berger, political editor for the Des Moines Register, joins CBSN's "Red & Blue" with the latest.
