CALDWELL, Idaho — Canyon County voters will head to the polls on May 19, 2026, for the Idaho Primary Election, with dozens of races and local measures on the ballot ranging from statewide offices to Canyon County seats and several fire district and school levies. Polls across the county will be open from 8:00 a.m. to 8:00 p.m.
What’s on the Ballot
The May 19 primary covers a wide range of offices and measures. At the federal level, Canyon County voters will weigh in on candidates for United States Senator and United States Representative for District 1. Statewide races include Governor, Lieutenant Governor, Secretary of State, State Controller, State Treasurer, Attorney General, and Superintendent of Public Instruction, along with seats on the Idaho Supreme Court and Court of Appeals.
At the legislative level, voters in Legislative Districts 9, 10, 11, 12, 13, and 23 will cast ballots for State Senator and both State Representative positions. Canyon County seats up for a vote include County Commissioner Districts 1 and 2, Clerk of the District Court, County Assessor, County Coroner, County Treasurer, and Precinct Committee Persons. Judges of the 3rd Judicial District are also on the ballot.
Several local taxing measures are also before voters, depending on residential location. These include a Middleton School District Supplemental Levy, a two-year temporary budget levy increase for Middleton Rural Fire District, a levy increase for Parma Rural Fire Protection District, and a two-year temporary budget levy increase for Star Fire Protection District.

Early Voting and Polling Locations

Impact on Canyon County Residents
The May primary carries significant weight for Canyon County families. Beyond statewide races, local taxing measures — particularly fire district levies and the Middleton school supplemental levy — will directly affect property owners and residents in those districts. Fire protection and school funding questions are among the most tangible budget decisions voters in rural Canyon County communities face, and the outcomes will shape local services for the next two years or more.
The county commissioner races in Districts 1 and 2 are also of note, as Canyon County commissioners hold authority over land use, county budgets, and a range of administrative functions that affect daily life across the Treasure Valley.
