Elections & Voter Records

The Malheur County Clerk's Office administers all elections affecting Ontario voters, operating from 251 B Street West, Suite B, Ontario, OR 97914 (phone: 541-473-5151, website: https://www.malheurco.org/clerk). The Elections Division handles every aspect of the process, from voter registration and ballot preparation to polling place assignments, absentee voting, vote counting, and certification of results for federal, state, county, and municipal contests. Oregon eliminated traditional polling places years ago, conducting all elections entirely by mail under ORS 254.465-254.474.
Voters receive their ballots approximately 18-20 days before each election and return them either by mail with prepaid postage or by dropping them in official ballot boxes scattered throughout Malheur County, including several locations across Ontario. Registering to vote happens online at https://sos.oregon.gov/voting/Pages/registration.aspx, the centralized portal maintained by the Oregon Secretary of State. The state offers same-day voter registration extending through Election Day itself, though registering at least 21 days out ensures ballots arrive by mail with time to spare. Registration requires an Oregon driver license or ID number, or the last four digits of a Social Security number. Oregon's Motor Voter law (ORS 247.017) automatically registers eligible citizens when they obtain or renew driver licenses unless they specifically decline. Updating addresses or party affiliation can be done online anytime. Municipal elections for the Ontario City Council and Mayor typically occur in November of even-numbered years, coordinated with state and federal general elections. The city operates under a council-manager structure with six council members elected by ward and a mayor elected at-large. Upcoming municipal elections are scheduled for November 4, 2025 (if positions are contested that year) or November 3, 2026. Candidate filings for city offices go through the Malheur County Elections Office, which manages ballot preparation. Local measures, charter amendments, and tax levies also appear on ballots, governed by Oregon's initiative and referendum statutes. Since Oregon conducts voting entirely by mail, no traditional polling places exist. Instead, the Malheur County Clerk maintains secure drop box locations throughout Malheur County. Ontario residents can deposit completed ballots at boxes positioned at the Malheur County Courthouse (251 B Street West), Ontario City Hall (444 SW 4th Avenue), and additional publicly accessible sites listed at https://www.malheurco.org/clerk. Drop boxes remain available around the clock but close promptly at 8:00 PM Mountain Time on Election Day. Ballot tracking is available online through https://sos.oregon.gov/voting, allowing voters to confirm when their ballot was received and tallied. Public election records in Oregon include the statewide voter registration database (with certain personal details redacted under ORS 247.965), campaign finance reports filed through the Oregon Secretary of State's ORESTAR system at https://sos.oregon.gov/campaign-finance, candidate filing information, precinct-level results, and abstract of votes. The county posts unofficial results on election night and certified tallies after canvassing at https://www.malheurco.org/clerk. Individual voter history—showing which elections a person participated in, not how they voted—is public record, as are campaign contribution and expenditure reports for all state and local candidates and political committees. During the November 2024 presidential election, Malheur County recorded approximately 60-65% voter turnout with roughly 7,500-8,000 ballots cast from about 12,000 registered voters. The county has historically leaned conservative, with Republican candidates typically prevailing by substantial margins in federal and state contests. Detailed precinct breakdowns are available from the Malheur County Clerk. The November 3, 2026 general election will present several major races for local voters. Oregon's Governor position will appear on the ballot (four-year term), as the governorship is up in 2026. All four of Oregon's U.S. House seats will be contested; Ontario falls within Oregon's 2nd Congressional District, covering the eastern two-thirds of the state. One U.S. Senate seat may be up depending on the cycle (Oregon holds Class II and Class III seats). All Oregon State Senate and State House seats will be on the ballot, including Senate District 29 and House District 58 covering the Ontario area. County offices typically on the 2026 ballot include Malheur County Commissioners (three-member board with staggered four-year terms), County Clerk, County Assessor, County Sheriff, and District Attorney. Ontario city council positions may also face contests. Voters should check https://www.malheurco.org/clerk for candidate filings and ballot measure language as the election approaches. Voters who don't receive their ballot by mail due to address issues or late registration can request a replacement from the Malheur County Clerk's office through Election Day. Ballots can be mailed back (postage-free as of 2024) or dropped in official boxes. Voters with disabilities can request assistance or use accessible ballot marking devices. Military and overseas voters receive special accommodations under the Uniformed and Overseas Citizens Absentee Voting Act (UOCAVA) and may receive and return ballots electronically in certain cases. Oregon requires no voter ID to register or vote; signature verification on the return envelope serves as the primary security measure.
