Phil Hart

Sen. Phil Hart is the Republican incumbent for Idaho Senate District 2, covering Shoshone County and parts of Kootenai and Benewah counties in North Idaho. He is seeking re-election in the May 19, 2026 Republican primary; the general election is November 3, 2026.

Background

Hart, approximately 70, earned a B.S. in civil engineering from the University of Utah in 1980 and an M.B.A. from the Wharton School at the University of Pennsylvania in 1984, per his Idaho Legislature member profile. He is a licensed structural and civil engineer, a small business owner, and a published author. He resides in Kellogg in Shoshone County and previously lived in Athol in Kootenai County. He has one daughter, Sarah. Affiliations include the American Legislative Exchange Council (ALEC), Gun Owners of America, and the NRA.

Political Career

Hart was first elected to the Idaho House in 2004 and served four terms (2004-2012), as documented by Ballotpedia. He returned to the Legislature as Senator for District 2 in December 2022 and was re-elected in 2024 with approximately 57 percent in the primary. He sits on the Senate Resources & Environment, Finance, and Transportation committees in the current biennium.

Policy Positions

Hart's 2026 platform emphasizes pro-life policy, Second Amendment protection (he co-sponsored the 2010 Firearms Freedom Act), state control of federal lands, "food and health freedom," parental rights and homeschooling, opposition to federal mandates including Real ID, and lowering or eliminating state income taxes. In prior House sessions he authored HB 82 (2007) to eliminate the grocery tax and HB 454 (2010) to replace the income tax with a sales-tax increase, HB 263 (2009) and HB 699 (2010) requiring school district checkbooks online, and the 2011 Wolf Emergency Bill transferring wolf management to the state.

Political Alignment

The 2025 Idaho Freedom Foundation Freedom Index scored Hart at approximately 90.5 to 92.6 percent (A grade), placing him among the most reliably IFF-aligned senators. Hart has a documented decades-long tax-protest history that resulted in the Idaho Supreme Court upholding rulings against him in 2012. Per Idaho Press coverage, Hart stopped filing state and federal income-tax returns starting in 1996, claiming they were unconstitutional — a position courts repeatedly rejected. He owed the state more than $53,000 plus interest and the IRS approximately $550,000 to $586,000 at various points including penalties. In 2011, while serving on the House Revenue and Taxation Committee, he gave up a vice-chairmanship to avoid an ethics sanction over the same tax issues and was removed from the committee. In 1996 he illegally cut trees from state school endowment land for his Athol log home. He settled the IRS case in 2015 with a nine-year payment plan and allowed the auction of his Athol home; bankruptcy court records show he had transferred assets to a trust with the admitted goal of shielding them from tax authorities. In October 2024 constituents sent a letter to the Idaho Secretary of State requesting an investigation into whether Hart actually resides in his registered Kellogg home, alleging it was unoccupied and under long-term construction; they cited a private investigator's observation that Hart stayed at a Hayden office outside the district. Hart told reporters he is present in his Kellogg home "nearly every day."

Campaign and Endorsements

Per Idaho Sunshine, Hart's 2026 campaign is supported by approximately $2,628 in independent expenditures from the Kootenai County Republican Central Committee and Bonner County Republican Central Committee. He is recommended in the KCRCC voter guide and endorsed by the Bonner County Republicans.
