(d)
Although a Democratic organization, club or association described in paragraph (a) may, in its discretion, permit within its membership persons
holding membership in more than one such organization, in all votes taken for endorsement of a nominee for
public office or party position such multiple membership holder may not vote on such endorsement in any such organization if the member has already voted on such endorsement in any other such organization.
The writ of quo warranto,
although rarely sought, is available to challenge the right of
public officials to
hold the
offices to which they claim entitlement.
