Gannon lives in Boise and is running unopposed in the May 19, 2026, Democratic primary, per Ballotpedia. He is seeking his eighth consecutive term in District 17A and is one of the longest-serving members of the Idaho Democratic caucus.

Background

Gannon was born in Ross, California. He earned a Bachelor of Arts from the University of California, Davis and a Juris Doctor from the University of California, Hastings College of Law, per his VoteSmart biography. He also attended the U.S. Army Reserve Judge Advocate General School and served in the military on standby reserve. He works as a part-time attorney and has been involved in six state Supreme Court and Court of Appeals decisions, per Ballotpedia. Gannon has lived on the Boise Bench for many years, where he raised his children, helped the local PTA, and served as a neighborhood leader, as described on his campaign website. He is married to Bev and has two children. Before entering the legislature, he served as Director of the New York Irrigation District from 1989 to 1990, winning election after becoming frustrated with paying assessments for water his neighborhood could not access and securing the release of 400 homes from the district. He also served on the Boise Project Board of Control and the Boise School District Facilities Steering Committee from 2005 to 2006, per his Idaho Legislature biography.

Political Career

Gannon was first elected to the Idaho House of Representatives in 1990, serving one term from 1990 to 1992, per Wikipedia. He returned to the legislature in 2012, winning District 17A, and has held the seat continuously since, running unopposed or with only token opposition in most cycles. In 2024 he ran unopposed in both the primary and general election. Gannon currently serves on the House Judiciary, Rules and Administration Committee, the State Affairs Committee, the Transportation and Defense Committee, and the Ethics Committee, per his Idaho Legislature biography. His committee history has also included Finance, Business, and various others across his tenure. His most sustained constituent service campaign has been pressuring the Veolia water utility to address chronic brown water problems on the Boise Bench. In 2019, he organized a public forum at Whitney Elementary School that drew significant attention to the issue, as covered by KTVB. In 2020, he and three other residents intervened in a Veolia rate increase proceeding at the Public Utilities Commission, resulting in a settlement that tied rate increases to service improvements. By 2021 Veolia had begun a $1.5 million rehabilitation of the Taggart Well and pipe replacement, per his campaign website. In 2022, Gannon developed a bipartisan bill with a Republican colleague allowing cities to rebate property taxes to low-income homeowners. The bill passed and Boise has since rebated $1.2 million annually to help lower-income homeowners remain in their homes, as reported by KTVB. He also authored two 2022 bills requiring PERSI and state investment funds to divest Russian bonds and currency following Russia's invasion of Ukraine, both of which passed with bipartisan support, per KTVB. In 2023, he co-sponsored legislation requiring a major corporation to pay property taxes to the tax base, providing modest relief for Ada County taxpayers. He was an active leader in Idaho's Medicaid expansion initiative from 2017 to 2018, per his Idaho Legislature biography.

Policy Positions

Gannon's documented legislative priorities center on water quality, property tax fairness, voting rights, education funding, grocery tax repeal, and state employee compensation. On water, his multi-year Veolia campaign reflects a constituent-service approach to infrastructure accountability. On property taxes, he has supported bipartisan mechanisms to give cities and counties tools to provide relief to low-income homeowners. On education, he has supported the Idaho Launch scholarship program, which he notes has benefited more than 100 students in District 17, per his campaign website. On voting rights, he has fought legislation that would restrict voting access. On compensation, he has advocated for state employee and PERSI retiree pay increases that keep pace with inflation. He opposed legislation to allow 80-mph truck speeds on portions of I-84, citing quality-of-life concerns for Bench residents.

Political Alignment

Gannon is a Mainstream Democrat whose legislative record reflects the practical, constituent-centered approach of a long-tenured representative in a reliably Democratic urban district. His bipartisan legislation on property tax rebates, Russian divestment, and juror pay reflects a willingness to work across party lines on issues with broad constituency support. His involvement in the Medicaid expansion initiative and his consistent support for education funding and voting rights place him within the governing wing of Idaho's Democratic caucus without strong ideological activist markers.
