Support for same-sex marriage is now in the Democratic Party preliminary platform. Once approved by the full platform committee and voted on at the convention, same-sex marriage will have the party's formal support.
But as Democrats institutionalize their support for same sex-marriage, their relationship with the party's most loyal constituency, black Americans, becomes increasingly uneasy.
A new survey just released by the Pew Forum on Religion & Public Life shows 65 percent of Democrats support same-sex marriage compared to just 40 percent of blacks.
A group of 3,700-plus black pastors, the Coalition of African-American Pastors, under the leadership of the Rev. William Owens, has moved to formally oppose the Democratic Party and President Barack Obama on this issue.
The group is spearheading a "Mandate for Marriage" campaign to gather 100,000 signatures on a petition declaring support for traditional marriage. The petition also calls for Obama "to repudiate his assertion that gay marriage is a civil right."
