The gay and lesbian community has been a reliable source of campaign money, but the president's equivocating clearly created some tension. From the NYT:
On Thursday, Mr. Obama is to attend a fund-raiser in Los Angeles at the home of the actor George Clooney, which is expected to raise about $12 million, much of it from Hollywood people active in the gay-rights cause. On Monday, Mr. Obama is scheduled to speak at a campaign fund-raiser and reception of the Lesbian, Gay, Bisexual and Transgender Leadership Council in New York City, where the special guest is the singer Ricky Martin, who is gay. On June 6 Mr. Obama is scheduled to return to Los Angeles to speak at a gala benefiting the gay, bisexual and transgender community, with tickets costing up to $25,000. And this summer, Democrats will begin meeting to draft the party's platform for the national convention that will nominate Mr. Obama in September, and some gay-rights activists are pushing to include language endorsing same-sex marriage. The president and his advisers in the White House and at the campaign headquarters in Chicago knew Mr. Obama would repeatedly have to parry questions and criticisms on the issue. That prospect, several Democrats said, suggested that the greater political risk for Mr. Obama was not in coming out for same-sex unions but in appearing to be politically calculating, especially given that most supporters believe he personally has favored same-sex unions.
From the Washington Post:
One in six Obama's 2012 campaign bundlers are gay, according to research conducted by the Post's Dan Eggen and T.W. Farnam. Couple that fact with the news earlier this week that George Soros, one of the most prominent Democratic major donors in the country, was directing his contributions to grassroots groups rather than the super PAC expected to fund TV ads supporting Obama and it's clear that the president badly needs a heavy investment from Hollywood and Silicon Valley. And those two communities are heavily in favor of gay marriage.
