IDAHO FALLS, Idaho — Bonneville County election officials have released the early voting schedule for the upcoming May 20, 2025, primary election, giving residents across Idaho Falls, Ammon, Iona, Ucon, and surrounding communities a clear window to cast their ballots ahead of Election Day.
The Bonneville County Clerk’s Office confirmed the dates and locations for early in-person voting, part of an ongoing effort to provide residents with flexible options for participating in the democratic process. Officials emphasized the importance of voters understanding the specific dates and procedures, particularly as Idaho’s closed primary system requires voters to be affiliated with a recognized political party to participate in partisan races.
Early Voting Dates and What Voters Need to Know
Early voting in Bonneville County for the May 20 primary is scheduled to begin in early May, with the Bonneville County Clerk’s Office serving as the primary location for residents to cast ballots before Election Day. Voters are encouraged to contact the Clerk’s Office directly or visit the county’s official website to confirm the most current hours of operation and any location details, as scheduling can be subject to administrative updates.
Idaho law requires voters participating in a party primary to be registered with that party. Residents who are unaffiliated or registered with a party other than the one whose primary they wish to participate in must update their registration before the deadline. In Idaho, the voter registration deadline falls 25 days before an election, meaning residents who have not yet registered — or who need to change their party affiliation — should act promptly to ensure eligibility.
Election officials in Bonneville County have encouraged voters to verify their registration status well in advance. Idaho offers online voter registration through the Idaho Secretary of State’s website, making the process accessible for residents throughout East Idaho.
What’s on the May Primary Ballot in Bonneville County
The May 20, 2025, primary election in Idaho will feature a range of local, county, and statewide races. Bonneville County voters can expect to see contests for local government positions, as well as state legislative races representing the districts that cover Idaho Falls and the broader Bonneville County region. Local school board positions and other nonpartisan offices may also appear on the ballot depending on the jurisdiction.
Primary elections serve as the mechanism by which Idaho’s recognized political parties select their nominees for the general election. Given the heavily Republican-leaning composition of Bonneville County and much of East Idaho, primary contests often carry significant weight in determining the direction of local and state representation.
Races tied to Idaho Falls, Ammon, and other Bonneville County communities carry direct implications for decisions ranging from infrastructure investment along Highway 20 and I-15 corridors to education policy affecting the Idaho Falls School District and Bonneville Joint School District. Fiscal responsibility and limited government principles frequently factor into the debates that define competitive primary matchups in this region.
How to Prepare Before You Vote
Bonneville County election officials recommend that voters take several steps before arriving at the polls, whether voting early or on Election Day. Bringing a valid form of Idaho identification is required under state law. Voters should also review a sample ballot in advance, which is typically available through the Bonneville County Clerk’s Office or the Idaho Secretary of State’s election portal.
Residents with questions about polling locations, accessibility accommodations, or absentee ballot options are encouraged to contact the Bonneville County Clerk’s Office directly. Absentee voting by mail is available in Idaho, and applications must be submitted by a deadline set prior to Election Day.
