Republicans in Indiana are focusing on retaining three congressional seats without incumbents and targeting incumbent Democrat Frank Mrvan in the 1st District, which has become more conservative due to a recent redistricting. In Michigan, Democrats are at risk of losing their slim House majority, which could hinder Governor Whitmer's legislative agenda, as they face tight elections in several districts. In Illinois, Democrats are working to defend pivotal congressional seats, with close races for first-term representatives Eric Sorensen and Nikki Budzinski against Republican challengers. Meanwhile, in Ohio, Democrats are defending three crucial congressional seats, including long-serving Rep. Marcy Kaptur, who faces a strong challenge from Republican Derek Merrin. The political landscape across these states reflects intense competition as both parties aim for control of the U.S. House. Key issues influencing these elections include economic concerns, reproductive rights, and voter turnout strategies.
