§ 5-304. Enrollment; change of enrollment or new enrollment by
previously registered voters. 1. A registered voter may change his
enrollment in the manner prescribed by this section.

2. The term "change of enrollment" shall apply to applications by a
registered voter already enrolled in one party to enroll in a different
party, or to delete his enrollment in any party, or an application by a
registered voter not enrolled in any party to enroll in a particular
party.

3. A change of enrollment received by the board of elections will take
effect immediately, provided however, any change of enrollment received
by the board of elections after February fourteenth and before or on
seven days after the June primary shall take effect on the seventh day
after the June primary.

4. Registered voters may apply for change of enrollment personally by
mail to or by appearing before a county board of elections or by
appearing before a board of inspectors. If the applicant has appeared in
person and if the board finds that he or she is properly registered, it
shall provide the applicant with an application form for voter
registration by mail which shall be treated as an application for change
of enrollment filed pursuant to this section. If the voter has applied
personally by mail, the county board of elections shall mail him or her
an application form for voter registration by mail as provided by this
chapter. If a registered voter submits an application form for
registration or enrollment as provided by this chapter, from the
residence address from which he or she is then registered, and such form
reflects a change of enrollment, the county board of elections shall
treat such form as an application for change of enrollment filed
pursuant to this section. If such application form also sets forth a new
address within the same city or county, the board of elections shall
also treat such form as an application for transfer of registration
pursuant to section 5-208 of this article. If a voter has cast a ballot
in an affidavit ballot envelope on which such voter claims a party
enrollment different from the enrollment in the records of the board of
elections, such affidavit shall be treated as an application for change
of enrollment.
