New Jersey's voter registration form does not provide a check-off for political party affiliation. A newly registered voter or voter who has never voted in a political party primary election can declare party affiliation at the polling place on the day of a primary election. In New Jersey, a primary election is only held for the Democratic and Republican parties. A voter may also file a political party declaration form to become a member of a political party. If a declared voter wished to change party affiliation he or she must file a declaration form 50 days before the primary election, in order to vote.
