Vote by mail is a method of distributing ballots for an election. Instead of using traditional polling places where voters go to cast ballots on election day, a ballot is automatically mailed to each registered voter. The ballot is then voted on and returned to the county election office to be counted.
Every county provides privacy booths where you can mark your ballot. Usually, you can drop off your completed ballot at the same location. Call your county election office if you need to locate and use a privacy booth.
