State Conservative Party Chairman Michael Long will not allow Janis Castaldi, a married lesbian candidate for the New York state Senate, to run on his party's line.

Castaldi's campaign to unseat Democratic Senator David Carlucci received the nod of the Republican Party committees and Conservative Party branches in Westchester and Rockland counties.

According to the New York Daily News, the groups were unaware that Castaldi married her wife in Connecticut in 2009.

“Castaldi needs a waiver from the state Conservative Party to run on its line, since she is not registered as a Conservative and the Senate district crosses county lines,” the News reported.

“She may be the nicest person in the world. She may be the most conservative person in the world,” Long told the paper, “but we, the Conservative Party executive committee, drew a line in the sand on the issue of same-sex marriage, and anyone who is for it will not be getting our endorsement.”

Long added that the Westchester County Conservative Party is no longer backing Castaldi's campaign.

Long had previously said his party would not support any candidate who is not opposed to gay nuptials.

Erica Pelletreau, a spokesperson for the Empire State Pride Agenda, the state's largest gay rights advocate, called Long's dismissal of Castaldi's campaign a “disturbing, vicious and mean-spirited attack.”
