Defenders of Maryland's new same-sex marriage law say they took in an eye-popping quarter of a million dollars last night at a Chevy Chase fundraiser.

The soiree, hosted by philanthropists Susie and Michael Gelman, was attended by Gov. Martin O'Malley and Lt. Gov. Anthony Brown, said Kevin Nix, a spokesman for Marylanders for Marriage Equality. About 70 attended, he said.

The state's new law allowing gays to marry is set to be on the November ballot, and advocates on both sides have been blasting out email solicitations in recent days.

The Maryland Marriage Alliance, which wants to defeat the bill, this morning asked for money and highlighting high-profile support on their on their side: They noted that a board member of the NAACP stepped down in protest after the civil rights organization agreed to back same-sex marriage. 

Neither side will have to report their finances until October, due to the state's antiquated disclosure laws on ballot initiatives.
