The last day a registered voter can change their political party affiliation before the 2026 State Primary Election is Tuesday, June 2, 2026. Per state law, voters may not change their party affiliation 90 days before a primary. 

The Supervisors of the Checklist will meet on June 2 from 7 to 7:30 p.m. at the City Clerk's office at City Hall, 288 Central Ave. The supervisors will register new voters, record changes of address, name and party affiliation, and make other necessary corrections to the checklist.

The Primary Election will be held on Tuesday, Sept. 8, 2026, with the General Election on Tuesday, Nov. 3. At the election, voters will cast ballots for county, state and federal offices. 

Voters domiciled in Dover may change their party affiliation at the City Clerk's Office, or any scheduled meeting of the supervisors of the checklist except between the first day of the filing period for the primary election and the date of the primary election itself.

Registered voters may check their political party affiliation through the Secretary of State’s Voter Information Lookup. The voter must enter their last name, town/city, and date of birth, and complete the security entry.
