A panel drafting the Republican Party’s platform on Monday rejected a push to moderate the party’s stance on same-sex marriage, voting sharply against a proposal that backers said would attract LGBT voters into the GOP tent.

“I’m not here asking you to endorse my own constitutional rights … I’m only asking you to recognize that many Republicans, many of the Republicans that sent us here to do work this week in shaping our party’s platform, agree with me, and we should not be excluded from our party,” said Rachel Hoff, a openly gay delegate from Washington D.C., at a meeting of the GOP Platform Committee here.

Hoff rattled off statistics suggesting sharply changing views on marriage among young Republicans. “If our party wants a future, we should be mindful of these statistics, and we must evolve,” she said.
