Brooke Green: Democratic incumbent for Idaho House District 18, Seat B

Brooke Green is the Democratic incumbent for Idaho House District 18, Seat B, on the November 3, 2026 general election ballot. Her opponent is Libertarian Joseph Bishop. Green won the May 19, 2026 Democratic primary unopposed with 2,488 votes, according to Idaho Secretary of State certified results. She has held the seat since first winning it in 2018 and is seeking a fifth term.

Background

Green was raised in Los Alamos, New Mexico, and has spent 28 years in Idaho as an adult, plus earlier summers here as a child. Her father was a biologist and her mother worked at Los Alamos National Laboratory. In her CBS2/FOX9 candidate survey, she wrote that spending summers in Idaho after her parents divorced "shaped my belief that families can take many forms through unique paths."

She holds degrees in communication and marketing technology from Boise State University and a master's degree in business administration from Northwest Nazarene University, per her official Legislature biography. Her career spans nonprofit work and transportation planning. She worked at the Ada County Highway District and is now an Associate Transportation Planner at Kittelson & Associates. She lives in Boise with her spouse, Leo. They have one son.

Legislative record

Green serves on the House Business, Ethics and House Policy, State Affairs, and Transportation and Defense committees, according to her official Legislature biography. Her most consequential assignment is the Joint Finance-Appropriations Committee, the joint House-Senate panel that writes the state budget. She was the only House Democrat on the committee during the 2026 legislative session, a distinction she cited in her own CBS2/FOX9 survey response.

She addressed the state's recent budget shortfalls in her survey response. "Idaho is not facing an inevitable budget crisis, we are creating one through the choices we make," she wrote. She argued that cutting Medicaid, transportation, education, and corrections spending does not make the costs disappear but shifts them to local hospitals, counties, and law enforcement. She favors drawing on the state's roughly $1.7 billion in reserve funds for one-time infrastructure needs and deferred maintenance. "I know there is a difference between fiscal responsibility and simply refusing to spend," she wrote.

House Bill 134

Green's signature legislative achievement grew out of her own medical care. She was diagnosed with breast cancer in 2024 and began chemotherapy in 2025. Days after her first diagnosis, her radiologist raised the issue of supplemental screening for high-risk patients. Green then sponsored House Bill 134, which requires health insurance plans to cover supplemental breast cancer screening, including MRI, for people at high risk due to personal or family history, genetic predisposition, or other factors.

The bill drew more than two dozen cosponsors from both parties. It passed the House 62-6 and the Senate 25-10, and Gov. Brad Little signed it in March 2025. It took effect January 1, 2026. "I've been here for seven years and I've carried several bills, but this one is by far the most meaningful one … Because it's going to help so many Idaho and women," Green told the Idaho Capital Sun.

The bill's passage became personal for the Legislature. Several of Green's colleagues, including Republicans Mike Pohanka, John Shirts, and Jaron Crane, shaved their heads at a Boise salon to support her treatment and raise awareness of breast cancer screening. "Breast cancer isn't a partisan thing," Green told the Idaho Capital Sun. "It brings people together in the worst kind of ways, and gets everybody in support of a cause."

Gov. Little highlighted her work in a written statement when he signed the bill. "I want to highlight Representative Brooke Green as she has courageously battled breast cancer, all while serving in the legislature this session and bringing meaningful legislation forward," he said. "HB 134 ensures access to life-saving breast cancer screening for at-risk individuals, reducing long-term treatment costs for Idahoans, hospitals, and insurers." The law does not apply to self-insured employer health plans, such as those at large companies, because Idaho cannot mandate those plans under federal law.

Where she stands

In her survey response, Green listed her top priorities for District 18: "strengthening transportation funding to address the continued maintenance backlog, continued support and funding for public education, and bringing attention to much needed long-term investments in infrastructure and housing affordability and availability." She also cited "supporting responsible economic growth, protecting Idaho's natural resources, and improving access to quality healthcare."

Asked what the Legislature had failed to address, she pointed to property taxes. Her answer, in her own words: "property tax relief for Idaho homeowners, specifically by indexing the homeowner's exemption." She explained that when the exemption stays stagnant while home values rise, seniors and long-term homeowners can see a growing share of their home's value taxed even if their income has not kept pace. Indexing it, she argued, would make relief automatic rather than dependent on the Legislature acting after homeowners already feel the pressure.

Campaign finance

Green's 2026 campaign has reported $8,700.00 in total contributions and $17,381.07 in expenditures, with an ending cash balance of $1,702.84, according to her Idaho Secretary of State Sunshine portal filing. In-state contributions account for $7,700.00 of the total, with $1,000.00 from out-of-state donors. Her top reported contributors include Ilana Rubel and John Paschke of Boise at $1,000.00 each, ACEC of Eagle at $800.00, and $500.00 each from the District 18 Democrats, the Coeur d'Alene Tribe, Micron Technology, Saint Luke's Health Plan, the Idaho Automobile Dealers Association, and Simplot.
