Are Republicans starting to change their position on same-sex marriage? Some gay marriage supporters think so.

“A 55 percent majority support marriage equality,” states a report accompanying a new TargetPoint-GQRR poll. “While young people are at the vanguard of change, this survey also shows increased support among older voters, Catholics, non-college educated voters, and Republicans.”

The poll results were presented at a Thursday kickoff event of Americans for Marriage Equality, a bipartisan group formed with the support of the Human Rights Campaign, a major gay rights organization.

The launch coincided with the one year anniversary of the U.S. Supreme Court decision striking down California’s Proposition 8 ban on gay marriage and a portion of the federal Defense of Marriage Act.

“Rather than uniform opposition, marriage equality now splits the right, with younger conservatives disagreeing with older conservatives,” says the report, titled “Victory in Sight.”
