AINews Summary

The biggest development is that Joni Ernst is not running again, leaving Iowa’s Senate seat open. The Democratic primary has narrowed to Zach Wahls and Josh Turek, and the full field now includes two Republicans and one Libertarian. Ballots are finalized ahead of the June 2 primary. The open seat adds uncertainty, but the race is still too early to call from these updates alone. The finalized field and active Democratic primary may keep the market volatile until nominees are set.
