Allows voter to vote in any political party primary by changing party affiliation at polling place on primary election day; allows mail-in voter to complete any political primary ballot.

This bill allows New Jersey voters to switch political party affiliations on primary election day. Voters can change their party at the polling place by signing a declaration form, or mail-in voters can complete any party's primary ballot to switch affiliation. The bill amends election law to remove the requirement that voters must have declared a party affiliation 55 days before the primary. It directly affects all voters participating in New Jersey's primary elections, whether voting in person or by mail. The key mechanism is the ability to declare a new party affiliation at the time of voting, rather than in advance.
