Idaho 2026 Elections: Races, Ballot Measures, and Polling

Election Overview

Idaho voters will participate in elections for U.S. Senate, Governor, both U.S. House seats, and state legislative positions in 2026. The Gem State's conservative political culture and Republican dominance mean that primary elections often determine outcomes in many races. Idaho's rapid population growth, particularly in the Boise metro area from transplants fleeing other states, is gradually shifting political dynamics and creating new tensions between longtime residents and newcomers, establishment Republicans and more conservative challengers.

Key Races

U.S. Senate

Idaho's U.S. Senate seat is up for election in 2026, with Senator Jim Risch eligible for a fourth term. First elected in 2008 after serving as Idaho's governor, Risch has focused on foreign policy, energy development, and Western land issues. As one of the most conservative members of the Senate, Risch's primary challenge (if any) will likely come from the right rather than the general election presenting a competitive race.

Governor

The Idaho gubernatorial race will determine the state's chief executive for a four-year term. Governor Brad Little, first elected in 2018 and re-elected in 2022, is eligible to seek a third term. The governor plays a crucial role in managing Idaho's explosive growth, natural resource policy, education funding, and relationships with the heavily Republican legislature. Republican primaries for governor have become increasingly competitive as different conservative factions compete for influence.

U.S. House of Representatives

Both of Idaho's congressional districts will be contested. District 1 covers northern Idaho including Coeur d'Alene and the panhandle, as well as parts of the Boise area. District 2 encompasses southern and eastern Idaho including Idaho Falls, Pocatello, and Twin Falls. Both seats are safely Republican in general elections, though primaries can be competitive and ideologically significant.

State Legislature

All 70 seats in the Idaho House of Representatives and 18 seats in the 35-member Idaho Senate will be on the ballot. Republicans hold overwhelming supermajorities in both chambers, making primary elections the primary venue for political competition. State legislative races often focus on education funding, tax policy, land use regulation, and the balance of power between state and local governments.

Ballot Measures

Idaho has a citizen initiative process that allows voters to place measures on the ballot through petition signatures, though the process has become more restrictive in recent years. The legislature can also refer constitutional amendments and other measures to voters. While specific 2026 ballot measures are still being determined, Idaho voters have recently considered initiatives on topics including Medicaid expansion, education funding, marijuana policy, and election procedures. Recent legislative changes have made it more difficult to qualify initiatives by requiring signatures from all 35 legislative districts rather than just 18. Proposed initiatives must gather signatures equal to 6% of registered voters in each legislative district for constitutional amendments. Check with the Idaho Secretary of State's office for confirmed ballot measures and signature deadlines as the election approaches.

How to Vote in Idaho

Voter ID Requirements

Idaho requires voters to present photo identification before voting. Acceptable forms include an Idaho driver's license, Idaho ID card, U.S. passport, tribal photo ID, or other photo ID issued by an Idaho agency. The address on your ID does not need to be current. If you don't have photo ID, you may present two forms of non-photo ID showing your name and address, or sign a personal identification affidavit attesting to your identity.

Absentee Voting

Idaho offers absentee voting to all registered voters without requiring an excuse. Absentee ballot requests must be submitted to your county clerk. Idaho does not have traditional early voting; voters must either vote absentee or vote in person on Election Day. Absentee ballots must be received by 8 PM on Election Day to count (postmarks do not extend this deadline).

Election Day Voting

Most Idaho voters cast ballots in person at their assigned polling place on Election Day. Polls are open from 8 AM to 8 PM in northern counties and 7 AM to 7 PM in southern counties (Mountain Time). Voters can find their polling place through the Idaho Secretary of State's website or by contacting their county clerk.

Party Affiliation for Primaries

Idaho has closed primary elections. To vote in the Republican primary, you must be registered as a Republican. The Democratic primary is open to registered Democrats and unaffiliated voters. Voters can change their party affiliation when registering or updating their registration, including on Election Day at the polls.

Current Political Landscape

Idaho is one of the most reliably Republican states in the nation, with the GOP dominating statewide offices and holding supermajorities in the legislature. However, Idaho's political landscape is more complex than its electoral outcomes might suggest, with significant tensions between different conservative factions and between longtime residents and recent transplants attracted by Idaho's low taxes, natural beauty, and conservative governance.

Geographic divisions create distinct political regions. The Boise metro area, Idaho's population and economic center, has grown rapidly and become somewhat more moderate, particularly in city elections. Northern Idaho, including Coeur d'Alene and the panhandle, has a strong libertarian and conservative Christian presence. Eastern Idaho, anchored by Idaho Falls and Pocatello, reflects both agricultural conservatism and the influence of the LDS Church. Rural areas throughout the state lean heavily Republican with local variations. Population growth is reshaping Idaho politics. The state has been one of the fastest-growing in the nation, with people fleeing California and other states seeking lower costs and conservative governance. This influx creates tensions over growth management, housing affordability, and maintaining Idaho's character. Key issues include managing rapid growth and housing affordability, education funding and school choice debates, property taxes and assessment practices, public lands management and access, water rights and agricultural protection, healthcare access in rural areas, and balancing development with preserving natural landscapes.
