Notable personal detailsLee Calhoun is a Republican candidate for the U.S. Senate in Montana in the 2026 election cycle. He is based in Whitefish, Montana and has described himself as a former solar-energy business owner who started a business designing and installing solar-energy systems for homes and businesses after moving to Montana around the mid-2010s. His campaign states he is running in the Republican primary and pledges to serve one term.
Opposes corporate tax abatements and supports holding corporations accountable for paying taxes that benefit local and state governments. Criticized legislation that would provide preferential tax treatment to a mining company and urged rejection of that bill. No comprehensive tax plan was found in campaign materials during this search.
Supports clean energy and distributed solar deployment and has been involved in residential net-zero projects and a Montana solar company; has signed industry letters supporting federal clean-energy investment. Does not appear to endorse Green New Deal–style or fossil-fuel phase-out language in available public materials.
Lee Calhoun has launched his campaign for the Montana Senate race, making him a new entrant in the 2026 contest. The race is also being shaped by a court ruling that blocked a new state law from ending Election Day voter registration for federal races, keeping same-day registration in place for now. That decision could affect how the Senate election is run, especially since the lawsuit says the restriction would have hit Native American and young voters hardest.
