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 
    In 2020, every registered voter will receive a ballot in the mail. Register now so there will be no delay in getting your 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.
