Four Democrats are competing in the May 5 primary for Indiana's 8th Congressional District for the chance to challenge Rep. Mark Messmer in November. Messmer is running for a second term after winning the seat in 2024 following the retirement of longtime Rep. Larry Bucshon, who held the seat from 2011 to 2025.
In his first term, Messmer has positioned himself as a small-business conservative and a vocal opponent of federal regulation. He has introduced the Heat Workforce Standards Act, which would repeal a Biden-administration OSHA rule on workplace heat-safety standards, calling it a "one-size-fits-all" federal mandate. A devout Catholic, Messmer has also been an active sponsor of anti-abortion legislation.
The district covers counties in southwestern Indiana, including Evansville, the district's largest city. Republicans have held the 8th District since 2011, but the district was historically known as "the Bloody 8th" for a long stretch of close races and party flips, including the disputed 1984 election that was decided by the U.S. House.
The four Democratic candidates are running on overlapping themes. None describes themselves as an establishment Democrat, and all four have framed their campaigns around reducing the influence of corporate money in politics.
WNIN and WFYI contacted each campaign to ask why the candidate is running and what their priorities are. For candidates who did not respond, information was gathered from their campaign websites and social media. Candidate statements have been lightly edited for length and clarity.
