What to watch in Tuesday's elections in Indiana, Ohio and Michigan

Key Points:

• President Donald Trump is targeting seven Republican state senators in Indiana with primary challengers after they opposed his redistricting plan, testing his influence over the GOP ahead of the midterm elections.
• Trump-backed groups have invested millions in these typically low-profile races, signaling potential consequences for Republicans who oppose him, especially in districts he won by large margins in 2024.
• Ohio’s primaries will determine candidates for key U.S. Senate and governor races, with former Sen. Sherrod Brown seeking a Senate comeback and Republican Vivek Ramaswamy leveraging his national profile and Trump alliance in the governor’s race.
• A special election in Michigan’s state Senate could shift the balance of power, with Democrats aiming to secure a majority by winning a closely contested seat in a district narrowly won by Biden in 2024.
• Recent special elections have favored Democrats, boosting their morale and alarming Republicans, though it remains uncertain if this trend will hold in the higher-turnout midterms.
