Primary Date: May 19, 2026
General Election: November 3, 2026
Democratic Party Overview
The Democratic Party in Idaho is implementing an expanded strategy aimed at competitive races in 2026. The Idaho Democratic Party recently launched its “All In for Idaho” campaign to recruit local candidates and grow voter registration, especially in rural and traditionally conservative communities that have often been overlooked.
U.S. Senate — Democratic Field
The sole Democratic candidate in the U.S. Senate primary is David Roth, a realtor and 2022 Democratic Senate nominee, who has filed to run in 2026.
David Roth, 43, brings name recognition from his previous statewide run and is running to provide Democratic voters with a strong option in a state dominated by Republicans. While Democratic votes are unlikely to overcome the GOP’s advantage, Roth’s experience on the ballot and support base could help maintain party momentum into 2026.
Age: 43 Gender: Male
Current Position: Consultant
Why he might win: While this seat is expected to remain Republican, Roth’s recognition among Idaho Democrats and his ability to unify the base makes him the leading candidate for nomination.
U.S. House — Democratic Fields
Idaho has two U.S. House districts, and Democrats have no current Democratic members of the Idaho House delegation.
ID-01
Kaylee Peterson – 33, Female, is an Artisan jeweler and former nominee in both 2022 and 2024.
Ken Brungardt – Age unknown, is a Retired painting contractor and passionate anti-MAGA Democrat.
Peterson has raised more funds and name recognition than Brungardt, giving her an edge in organizing and outreach.
Why she might win: Peterson’s repeat candidacies provide continuity and name familiarity across Democratic voters in Idaho’s most competitive congressional district, strengthening turnout and volunteer networks despite the overall Republican lean.
ID-02
Julie Wiley, age unknown, retired counselor.
Wiley’s strength in the Democratic primary is name recognition among local Democratic activists. Her service background and narrative about helping families and schools could resonate with primary voters who value lived experience.
