Mandy Peace: Democratic Nominee for Idaho Senate District 28

Mandy Peace ran unopposed in the May 19, 2026 Democratic primary for Idaho Senate District 28, receiving 946 votes, according to certified Idaho Secretary of State results. She will appear on the November 3, 2026 general election ballot against Republican incumbent Jim Guthrie of McCammon, who won a contested primary against David Worley.

Path to the Ballot

Peace's path to the nomination cleared early. Fellow Democrat Rosann Mathews had filed to run for the District 28 Senate seat but withdrew on March 6, 2026, eliminating the Democratic primary and leaving Peace as the nominee, according to Idaho Education News. District 28 covers Bannock, Power, and Franklin counties.

A Prior Run for Chubbuck City Council

The 2026 Senate race is not Peace's first campaign for public office. She ran for Chubbuck City Council Seat 4 in the November 5, 2025 municipal election and lost to incumbent Norman G. Reece Jr., receiving 1,063 votes to Reece's 1,590, or 40.07 percent to 59.93 percent, according to final results published by the Idaho State Journal.

Background in Emergency Response and Higher Education

Peace was born and raised in Chubbuck, where she is raising her own children. On her campaign site, she writes that District 28 "is home to me and my family in the fullest sense of that word" and describes her family's history of military and public service as spanning more than 100 years.

Her professional background includes work as a psychiatric technician and an EMT. She has served in the Medical Reserve Corps, Bannock County Search and Rescue, and Southern Bannock County Ambulance, and deployed with the Red Cross during Hurricane Katrina, according to an Idaho State Journal profile published April 6, 2026.

Peace now works in management and finance in higher education, managing budgets exceeding $15 million across five-year funding cycles and designing a budget-tracking system for resource allocation. Her volunteer work includes animal rescue, support for unhoused neighbors, foster-care support, and organizations focused on education and local business.

Campaign Events

In April 2026, Peace joined the other two District 28 Democratic candidates, Kim Jackman and Jayson Meline, for a series of meet-and-greet events across the district, per the Idaho State Journal. The tour opened in Power County on April 14 at the American Falls City Park South Shelter, with a $10 potato bar dinner, a silent auction, and a fundraiser, followed by a Franklin County event on April 18.

Platform in Her Own Words

Peace's campaign issues page lists five priorities: healthcare access, education and workforce development, public lands/agriculture/water, economic stability, and civic engagement and representation.

On healthcare, she writes: "Healthcare is a lifeline and every person in District 28 deserves access to quality care." She says she will "fight to protect state funding for critical access hospitals" and that mental health and addiction services "must be treated with the same urgency as physical health."

On education, she writes that she will "advocate for equitable education funding that doesn't leave rural schools behind" and supports expanded dual-credit and workforce training programs. She describes herself as "a first-generation college student and native Idahoan."

On natural resources, she writes: "I will be a consistent, vocal opponent of any effort to transfer or sell Idaho's public lands out of public hands." On water, she says she is "committed to protecting Idaho's water rights framework and ensuring farmers and ranchers have a real voice in water allocation decisions." She adds that she carries "deep respect for the Shoshone-Bannock people" and will work to strengthen the government-to-government relationship with the tribes.

On economic stability, she supports budget transparency, identifying grant opportunities that broaden the tax base, housing development that creates affordability while protecting the agricultural economy, and investment in rural roads, broadband, and utilities.

Campaign Finance

According to the Idaho Secretary of State's Sunshine portal, Peace's 2026 campaign reported $4,169.38 in total contributions, a $455.00 loan to her own campaign, $4,223.29 in expenditures, and $401.09 in cash on hand. All contributions came from in-state donors, including the Bannock County Democratic Central Committee, the Power County Democrats, and the Idaho Democratic Legislative Campaign Committee.
