LANSING, Mich.—Former Democratic state Sen. Curtis Hertel Jr. on Monday announced a campaign for Michigan’s 7th Congressional District, one of the nation’s most competitive House districts.
Mr. Hertel and another ex-state senator, Republican Tom Barrett, who launched his second run for the seat Sunday night, are the first to announce bids for the seat of U.S. Rep. Elissa Slotkin (D-Mich.). Ms. Slotkin, a Democrat, announced earlier this year that she would seek Michigan’s open U.S. Senate seat.
