A registered voter currently affiliated with a political party who wishes to change their party affiliation must file a Political Party Affiliation Declaration Form 55 days before a Primary Election.
A registered voter currently not affiliated with a political party may declare their party affiliation up to and including Primary Election day.
You can print and complete the Political Party Affiliation Declaration Form and mail or deliver to the Commissioner of Registration in your county or you can also file it with your municipal clerk. These cards are also available at your local Commissioner of Registration Office.
The Commissioner of Registration cannot accept faxed copies or an electronic transmission of Party Affiliation Declaration Forms, since an original signature is required.
