Josh Turek holds a strong lead in the June 2 Iowa Democratic Senate primary, reflecting trader assessments of his broad endorsements from figures like Pete Buttigieg and Tom Harkin alongside more than $8 million in supportive advertising from VoteVets. These resources have reinforced perceptions of Turek as the stronger general-election matchup against Republican nominee Ashley Hinson in a contest to flip the open seat. Zach Wahls remains the main challenger, drawing attention for his emphasis on grassroots appeals and criticism of outside spending, though recent polling and debate exchanges have shown limited movement in his position. The two minor candidates trail far behind with negligible visibility ahead of the primary.
