Recent polling in Iowa's Democratic primary for the open U.S. Senate seat has shown state Representative Josh Turek maintaining a substantial lead over state Senator Zach Wahls ahead of the June 2 vote. Turek's advantage stems from survey results indicating stronger support among likely primary voters, alongside arguments about electability against the Republican nominee in the general election. Both candidates have intensified campaigning in key areas like Des Moines, participating in debates that highlighted differences on issues such as immigration and outside spending. Wahls draws on prior statewide visibility, yet trader consensus reflected in current pricing aligns with Turek's polling edge and recent momentum. Minor candidates remain negligible factors in the race.
