Iowa Primaries: A Bellwether for National Control

Iowa's primary elections on Tuesday will determine candidates for key races that could shift control of Congress and the governorship. Both parties view the state as a battleground.

- Republicans tout policy wins but face headwinds from Trump's low approval and economic issues. - Democrats see openings on tariffs and the Iran war, despite their own brand being unpopular.

- Trump's last-minute endorsement in the governor's race tests party unity. - The outcome will have national implications for the midterm elections.

The primaries set the stage for a November sprint where Iowa's races will be closely watched as a bellwether for national political trends.
