The Daily Caller:

President Barack Obama’s campaign manager on Wednesday backed away from calls for the Democratic convention platform to endorse marriage licenses for same-sex couples.

“There is a process to go through this discussion,” said campaign manager Jim Messina. By the end of the September convention, he said, “we will have a platform,” but did not say whether it should include a marriage stance.

... Messina’s caution illustrates the deep division between the party’s wealthy progressive leadership and its vital — but socially conservative — blocs of Latino and African-American voters.

... Villaraigosa’s call for same-sex marriage to be approved by the Democratic Party’s platform is riskier for Obama, partly because supporters of traditional marriage have already won more than 30 state ballots that have defined marriage as between one man and one woman.

Those victories were aided by support from African-Americans and Latinos — two blocs that the Obama campaign sees as vital in the 2012 race.
