WASHINGTON — About two hours after declaring his support for same-sex marriage last week, President Obama gathered eight or so African-American ministers on a conference call to explain himself. He had struggled with the decision, he said, but had come to believe it was the right one.
The ministers, though, were not all as enthusiastic. A vocal few made it clear that the president’s stand on gay marriage might make it difficult for them to support his re-election.
“They were wrestling with their ability to get over his theological position,” said the Rev. Delman Coates, the pastor of Mt. Ennon Baptist Church in Clinton, Md., who was on the call.
In the end, Mr. Coates, who supports civil marriages for gay men and lesbians, said that most of the pastors, regardless of their views on this issue, agreed to “work aggressively” on behalf of the president’s campaign. But not everyone. “Gay marriage is contrary to their understanding of Scripture,” Mr. Coates said. “There are people who are really wrestling with this.”
In the hours following Mr. Obama’s politically charged announcement on Wednesday, the president and his team embarked on a quiet campaign to contain the possible damage among religious leaders and voters. He also reached out to one or more of the five spiritual leaders he calls regularly for religious guidance, and his aides contacted other religious figures who have been supportive in the past.
The damage-control effort underscored the anxiety among Mr. Obama’s advisers about the consequences of the president’s revised position just months before what is expected to be a tight re-election vote. While hailed by liberals and gay-rights leaders for making a historic breakthrough, Mr. Obama recognized that much of the country is uncomfortable with or opposed to same-sex marriage, including many in his own political coalition.
