Notable personal detailsJohn Calvin Fleming Jr. is a Louisiana politician, physician, and former U.S. Navy officer who has served as Louisiana State Treasurer since January 2024. He previously represented Louisiana's 4th Congressional District in the U.S. House of Representatives from 2009 to 2017. His background includes medical training at the University of Mississippi and service in the U.S. Navy from 1976 to 1982.
Supports eliminating personal income tax in Louisiana, opposes federal tax credits/subsidies such as 45Q for carbon capture, and emphasizes cutting government spending and limiting taxpayer-funded programs. Advocates reducing taxes and rolling back tax incentives he views as cronyism.
Supports repeal of the Affordable Care Act and legislative alternatives that would replace ACA provisions; has described the ACA as not fixable and opposed expansions of government-run healthcare. Advocates market-oriented reforms and policies reducing regulatory burdens on providers, including promoting health IT interoperability and pay-for-value approaches.
Supports stronger border security and enforcement, opposes executive amnesty and sanctuary-city policies, and has called for accountability for Department of Homeland Security leadership over perceived failures at the southern border. Has backed legislation to withhold federal funds from sanctuary jurisdictions and criticized policies that would regularize large numbers of undocumented immigrants.
The candidate opposes abortion and has supported federal restrictions and conscience protections for health-care providers; he has cosponsored legislation declaring life begins at fertilization and voted to prohibit federal funding for abortion and Planned Parenthood.
Opposes carbon capture and sequestration (CCS) projects and federal tax credits that support them (45Q), arguing they are dangerous, a misuse of taxpayer money, and can create eminent domain issues for landowners. Positions prioritize property rights and reduced federal subsidies for CCS while criticizing what he describes as cronyism in climate-related subsidies.
Supports strong Second Amendment protections and has a long record of sponsoring and passing pro-gun-rights legislation while opposing additional federal gun restrictions. Holds high ratings from major gun-rights groups and emphasizes defending lawful gun owners' rights.
John Fleming has entered Louisiana’s 2026 Republican U.S. Senate primary and has qualified for the May 16 contest, setting up a competitive race against incumbent Bill Cassidy and Rep. Julia Letlow. He is campaigning aggressively and casting both Cassidy and Letlow as too liberal, while the field trades attack ads over who is the most conservative. The broader policy backdrop includes debate over expiring enhanced ACA premium credits, an issue expected to affect costs and could surface in the campaign.
