Obama spoke at an evangelical church in Greenville, South Carolina earlier this month.
COLUMBIA, South Carolina (CNN) - Sen. Barack Obama's campaign is kicking off a series of Gospel concerts in Charleston tonight, meant to boost Obama's support among black voters in South Carolina. But what started as a local outreach project that would otherwise fly under the national radar has turned into a major headache for the Obama campaign.
The controversy also highlights the fact that Obama's desire to unite disparate voting blocs - especially religious voters - under his umbrella of "change" is not without some serious pitfalls for a Democratic presidential candidate.
When the campaign announced the lineups for the three-city "Embrace the Change!" Gospel tour last week, one name stood out to gay bloggers: Donnie McClurkin. The Grammy-award winning singer/preacher is on record as saying homosexuality is a choice, and that he himself was "once involved with those desires and those thoughts," but was able to get past them through prayer. To say the least, neither of those arguments are very popular in the gay, lesbian, bisexual and transgender community.
John Aravosis, a prominent gay blogger and co-founder of the web site AmericaBlog, led the charge against the Obama campaign, writing that the Illinois Democrat was "sucking up to anti-gay bigots" and "giving them a stage."
Once the story bubbled up into the mainstream media, the Obama campaign was taken by surprise. In competing to win over African-American voters in South Carolina against Sen. Hillary Clinton, Obama's efforts in the Palmetto State have been overwhelmingly targeted at African-American churchgoers.
The campaign here has vigorously promoted the candidate's faith, launching an effort in late September called "40 Days of Faith and Family," which used Bible study groups to tap into the black electorate. They have run three radio ads, one of which called Obama a “Christian family man,” all distributed on Gospel stations across the state.
Earlier this month, Obama appeared and spoke at an evangelical church in the traditionally conservative city of Greenville, where he demonstrated a casual familiarity with Christian vocabulary, telling the crowd to much applause that, "I am confident that we can create a Kingdom right here on Earth."
After that appearance, the Obama campaign told CNN that Republicans no longer had a choke hold on issues of faith and values.
"I think that what you're seeing is a breaking down of the sharp divisions that existed maybe during the '90s," Obama said. "At least in politics, the perception was that the Democrats were fearful of talking about faith, and on the other hand you had the Republicans who had a particular brand of faith that oftentimes seemed intolerant or pushed people away."
But on Tuesday, Obama was forced to confront the uncomfortable truth that some Christians and gays are a little more than just strange bedfellows, especially among blacks.
Obama issued a statement saying, "I strongly disagree with Reverend McClurkin's views and will continue to fight for these rights as president of the United States," but he argued that it is important to confront homophobia in the African-American religious community.
A September poll of African-Americans in South Carolina by Winthrop University and ETV showed that 62 percent of those surveyed said that "sex between two adults of the same sex" is "strongly unacceptable."
Obama held a conference call Wednesday with Joe Solmonese, president of the Human Rights Campaign, and announced that Rev. Andy Sidden, an openly gay South Carolina pastor, will appear at the same event as McClurkin on Sunday in Columbia.
Solmonese was not completely assuaged.
"I spoke with Sen. Barack Obama today and expressed to him our community's disappointment for his decision to continue to remain associated with Rev. McClurkin, an anti-gay preacher who states the need to 'break the curse of homosexuality,'" he said in a statement. "There is no gospel in Donnie McClurkin's message for gay, lesbian, bisexual and transgender people and their allies. That's a message that certainly doesn’t belong on any Presidential candidate's stage."
The State newspaper in Columbia also reported Friday that Obama organized a conference call Thursday night with gay and lesbian leaders. After the call, the South Carolina Gay and Lesbian Pride Movement announced they will hold a protest vigil outside Sunday's concert here.
Privately, Obama aides say they believe Obama is a candidate of real, transformational change, and that uproars like the McClurkin controversy are necessary speed bumps on the road to bringing people with opposing viewpoints together to air their differences.
Will Obama's refusal to kick McClurkin off the concert bill hurt him? Like many political squabbles, despite the national story, it depends how much the controversy resonates with voters in those crucial early states: Iowa, New Hampshire, Nevada and South Carolina.
And in South Carolina, where African-Americans make up about half of Democratic primary-goers, voters might not have that much of a problem with McClurkin at all.
