Howard County Executive Ken Ulman (D), who has been positioning himself to run for governor in 2014, is hosting a fundraiser Friday night to benefit the campaign to uphold the state’s same-sex marriage law.

Proceeds from the fundraiser, which is being held at the home of Ulman’s parents, will benefit Marylanders for Marriage Equality, the coalition leading the effort to keep Maryland’s law on the books.

State elections officially notified opponents of the law this week that they had collected enough signatures to force a statewide vote on the issue in November.

Last fall, all four 2014 hopefuls helped sponsor a fundraiser for Equality Maryland, a leading gay-rights group, as it geared up to fight for the same-sex marriage bill during the legislative session.

Lt. Gov. Anthony G. Brown (D) and Attorney General Douglas F. Gansler (D) both spoke at the event alongside O’Malley. Ulman and Comptroller Peter Franchot (D) did not appear but helped raise money, organizers said at the time.

More recently, Brown has helped raise money to aid the referendum, according to Marylanders for Marriage Equality.
