The National Organization for Marriage (NOM) insists Assemblyman David Weprin's support for gay marriage doomed his House bid.

The nation's most vociferous opponent of gay marriage spent $75,000 to ensure Ninth Congressional District voters knew that Weprin voted in favor of making New York the sixth state to legalize gay marriage.

Republican Bob Turner won Tuesday's special election to replace former New York Rep. Anthony D. Weiner, who resigned in June as a result of a sexting scandal.

While both candidates said they did not believe the election hinged on social issues, NOM is making certain it got its money's worth, releasing on Wednesday a survey that showed Turner supporters don't back gay marriage.

“This survey demonstrates what many people have been saying for a long time – David Weprin's vote in favor of same-sex marriage cost him the election to the U.S. House,” said NOM President Brian Brown. “NOM funded a major independent expenditure campaign in this race and the survey shows that marriage was a major factor in the race and cost Weprin the election.”

The survey found that 44 percent of respondents who oppose gay marriage said it was a factor in their vote.

“All you have to do is look at David Weprin's shocking loss to Bob Turner to understand that voting for same-sex marriage has consequences,” Brown said.
