PORTLAND — Supporters of legalizing same-sex marriage in Maine say they have exceeded a fundraising goal that makes them eligible for a $100,000 matching grant from a co-founder of Facebook.

A spokesman for the group Mainers United for Marriage tells the Bangor Daily News that the group had raised more than $121,000 as of Friday, and topped $100,000 on Thursday, the deadline for qualifying for the matching funds.

Chris Hughes, editor-in-chief of the liberal magazine The New Republic, who owns 1 percent of Facebook, and his fiance, Sean Eldridge, president of Hudson River Ventures and senior adviser to the national organization Freedom to Marry, promised the matching funds last month.

Maine residents will vote Nov. 6 on whether to allow marriage licenses to be issued to same-sex couples.
