Time Magazine explaining what happened in NY-9 yesterday:

In an area that includes large pockets of conservative Orthodox Jews, the 55-year-old Weprin — who is himself Orthodox — was hurt by his vote in favor of New York’s gay-marriage law. “There’s only one reason David Weprin is in trouble in race for a very safe Democratic seat: His support for same-sex marriage,” wrote Brian Brown of the National Organization for Marriage, which forked over $75,000 to defeat Weprin. In a recent Public Policy Polling survey, 29% of respondents said gay marriage was a very important issue.
