Election administrators take many steps to ensure that voters only cast one ballot in an election. Voters have to be eligible to receive a ballot. Election officials keep detailed records of who has already voted, and who has already requested and received a ballot in the mail. These steps make it difficult for someone to cheat, so voting twice is both easy to catch and extremely rare. Additionally, most state laws make this type of illegal activity a felony that is punishable by time in jail, large fines, or both.
