Where to Vote

  • Before an election, a sample ballot is sent to each registered voter telling the precinct number, the address of the assigned 
    voting place.
  • Absentee or voting by mail 
    If you are unable to vote in person, you can apply for a vote-by-mail ballot by contacting the Registrar of Voters from the 60th to the 7th day before election day. Or you use the application on the back cover of the sample ballot.

How to Keep Voter Registration Up to Date:

  • Always vote.
  • When you move within the county or change your name, request a change form from county voter registrar.
  • If you move out of county, you must re-register with the county of your new residence.
  • Address change must be completed 30 days prior to Election Day.
  • You may return to your former precinct to vote for 90 days after a move. 

Why Bother To Vote

  • Your vote does make a difference.
    Elections have been won by only one vote. American democracy is a participatory form of government.
  • Express your opinion - voting gives you the power. Voting is the most important right of citizenship because it is the only means you have of preserving all your other rights.
