COLUMBUS, Ohio (AP) — Democrats have won a key congressional seat and are defending two others in Ohio. Twenty-one-term U.S. Rep. Marcy Kaptur, the longest-serving woman in House history, declared victory over state Rep. Derek Merrin, a Trump-endorsed Republican, early Wednesday. However, The Associated Press had not yet called a winner in the 9th Congressional District. First-term Democrat Emilia Sykes remained in a tight race against Republican Kevin Coughlin, an ex-state lawmaker, in northeast Ohio’s 13th Congressional District. In southwest Ohio, incumbent Democrat Greg Landsman defeated Republican Orlando Sonza in Ohio’s 1st Congressional District.
