Voter registration in the United States
In the United States, such drives are often undertaken by a political campaign, political party, or other outside groups (partisan and non-partisan), that seeks to register persons who are eligible to vote but are not registered. In all states except North Dakota, registration on the electoral roll in the United States is a prerequisite to a person being able to vote at federal, state or local elections, as well as to serve on juries and perform other civil duties. Sometimes these drives are undertaken for partisan purposes, and target specific demographic groups that are likely to vote for one candidate or other; on the other hand, such drives are sometimes undertaken by non-partisan groups and targeted more generally.
