Dennison voters are served by the Clark County Clerk's Office, which administers all elections for the county. The office is located at 501 Archer Avenue, Suite 5, Marshall, IL 62441, phone (217) 826-8311. The County Clerk serves as the election authority under Illinois Election Code (10 ILCS 5/1-1 et seq.) and maintains voter registration records, prepares ballots, manages polling places, and certifies election results. Dennison residents can register to vote online at www.elections.il.gov through the Illinois State Board of Elections, by mail using a voter registration application, or in person at the County Clerk's office. Online registration requires an Illinois driver's license or state ID. The voter registration deadline is 27 days before any election for online and mail registration, though same-day voter registration is available at designated early voting sites and on Election Day at polling places under Illinois law. Grace period registration runs from 28 days before through Election Day. Valid identification or two forms of documentation showing current name and address are required. Dennison has no municipal government, so residents do not vote in city elections; instead, voters participate in federal, state, and county elections. Clark County voters elect county board members, county officers including Sheriff, Clerk, Treasurer, State's Attorney, Coroner, and Circuit Clerk, plus state legislators and federal representatives. In the November 2024 general election, Clark County reported voter turnout of approximately 68%, with 4,150 ballots cast out of approximately 6,100 registered voters, reflecting strong participation in the presidential election. On November 3, 2026, Clark County and Dennison voters will decide several important races. The 2026 general election will include Illinois statewide offices: Governor and Lieutenant Governor (four-year terms), Secretary of State, Attorney General, Comptroller, and Treasurer. U.S. Senate: Illinois' Class III Senate seat (currently held by Senator Tammy Duckworth) will be on the ballot in 2028, not 2026; however, Illinois' other Senate seat (Class II) is not up in 2026 either, so no U.S. Senate race will appear. All 118 Illinois House of Representatives seats (state legislature) will be contested, including the district representing Clark County. Clark County will also likely see races for County Board seats and potentially other county offices depending on term expirations. Dennison residents can find their assigned polling place by using the polling place lookup tool at www.elections.il.gov or by contacting the County Clerk. Illinois offers early voting beginning 40 days before an election at designated sites including the County Clerk's office. Vote-by-mail (absentee) ballots are available to any registered voter without requiring an excuse; applications can be submitted online, by mail, or in person up to five days before Election Day. Mail ballots must be postmarked by Election Day and received within 14 days after the election to be counted. Election records that are public in Illinois include voter registration lists (available for purchase for political purposes under 10 ILCS 5/1A-25), campaign finance reports (searchable at www.elections.il.gov through the State Board of Elections), candidate filing documents, and precinct-level election results. The County Clerk publishes unofficial results on election night and certifies official results within weeks following canvassing.
