Mark Grisanti, one of four New York Republican state senators who voted for gay marriage, won his GOP primary on Thursday.

Grisanti of Buffalo scored a comfortable victory – claiming about 60 percent of the vote – over his GOP rival, lawyer Kevin Stocker. Michael L. Amodeo defeated 2 competitors to become the Democratic nominee and face Grisanti on November 6.

The races of 2 other senators who helped New York become the largest state to approve gay marriage, Senators Stephen Saland of Poughkeepsie and Roy McDonald of Saratoga County, remained too close to call Thursday night. James Alesi of Rochester, the fourth senator, retired.

The four men faced criticism from conservatives over their votes in favor of the state's historic marriage equality legislation.

The campaign against Grisanti included an email flier sent to 300 people earlier this week which included sexually provocative images from gay porn studio Corbin Fisher. Rival Stocker condemned the ad, calling it disgusting.

Flanked by family members, Grisanti declared victory at the SoHo Bar in downtown Buffalo on Thursday night.
