WASHINGTON (AP) — One of the biggest stars of the left, congresswoman Ilhan Omar, is facing a challenge from the center in her primary in Minnesota on Tuesday. In Vermont, Democrats will choose a nominee for an open U.S. House seat who will likely make history as the first woman to represent the state in Congress. In Wisconsin, Democratic Rep. Ron Kind’s retirement opens up a congressional seat in a district that has been trending Republican. Minnesota is holding a special election to fill the remaining months of the term of Republican Rep. Jim Hagedorn, who died of cancer in February. Voters will also be picking nominees for a full term representing Hagedorn’s district.
