Mark Messmer — Republican Candidate for U.S. House in Indiana, 2026

Mark Messmer supports the SAVE America Act, which passed the House of Representatives. He stated that this legislation strengthens voter identification and citizenship verification standards to protect the integrity of federal elections. Messmer believes these measures ensure that every American citizen casting a vote will have that vote properly counted.

““Hoosiers are blessed to live in a State that runs secure and transparent elections. It is high time the federal government finally earns the trust of the American electorate by fixing our system of voting in federal elections,” said Rep. Mark Messmer (R-IN), in a press release from his office dated February 12, 2026. “Requiring voters to show identification is not a way of suppressing voter participation, but rather ensures that every American citizen casting their vote will have that vote properly counted. Strengthening voter ID and citizenship verification standards through the SAVE America Act will protect the integrity of future federal elections.””

Mark Messmer voted "Yea" on H.R. 6703, the "Lower Health Care Premiums for All Americans Act," in 2025, a bill aimed at reducing healthcare premiums. He supports broader healthcare reforms that seek to lower costs and expand access for citizens. Messmer introduced the "Heat Workforce Standards Act of 2025" to repeal a federal heat-safety rule, stating that heavy-handed regulations can increase costs and undermine business productivity. He is also actively working on legislation to reform prior authorization in healthcare.

“As a small business owner myself, I’ve seen how unwarranted, heavy-handed regulations can crush innovation, increase costs, and undermine the productivity of American institutions," Messmer said in a statement. "The Biden Heat Rule was never about safety, but was rather, unsurprisingly, focused upon expanding federal bureaucratic control over hard-working Americans.”

Mark Messmer received a 0% score from the League of Conservation Voters in 2025 and for his lifetime, indicating a lack of support for environmental legislation. He voted against the Reliable Power Act and measures to limit methane pollution. He also voted "Yea" on bills such as the Homeowner Energy Freedom Act and the Securing America's Critical Minerals Supply Act, as well as on Indiana state legislation that opposed energy-efficient buildings and participation in the Climate Registry. He did not answer specific questions regarding man-made climate change.

Rep. Mark Messmer supports legislation protecting the dignity of life from conception to natural death and is a member of the Pro-Life community.

Messmer affirmed his opposition to abortion in most cases and stated he would never give up fighting for those who cannot fight for themselves. He also voted "Yes" on the Pregnant Students' Rights Act.

“In my role in the House of Representatives, I am a reliable vote for the Pro-Life community and have been a sponsor of many pieces of legislation that provide for the needs of pregnant mothers, and the life they are carrying in the womb. I am honored to celebrate each person participating in this year’s March and I am grateful to be in a position to support the hopes of every Hoosier and American devoted to the sanctity of life. It is my great privilege to fervently promise that I will never give up fighting for those who cannot fight for themselves. Mr. Speaker, I yield back." — Rep. Mark Messmer, Remarks in the House of Representatives, January 23, 2026 (via Legistorm)”
