A group of African-American faith leaders plan to spend $1 million on an effort to strip President Barack Obama of 25 percent of the black vote that he garnered in 2008.

The new nonprofit group, God Said, announced the campaign on Tuesday, saying it was upset with Obama’s support of same-sex marriage,  The Daily Caller reports. The president won 95 percent of the black vote in 2008.

“The black community is among the most religious in America, and we are offended that President Obama has announced his support of same-sex marriage, that the NAACP has blindly supported the secular views of the Democratic Party, and that their national platform plainly supports same-sex marriage,” Apostle Claver Kamau-Imani, a God Said founder, said in a statement published by The Daily Caller. “I am confident that this message will be well received and acted upon on Election Day.”

The group, with 22 advisory board members, plans radio and television ads in Ohio, Virginia, North Carolina, Wisconsin and Florida. It also has a grass-roots component.

“During the 2008 elections, 70 percent of African-Americans voted to ban same-sex marriage in California while they also voted for Barack Obama for president,” Dr. Alveda King, niece of the Rev. Dr. Martin Luther King Jr., told The Daily Caller.

King also is black outreach director of the pro-life Priests for Life and is a Newsmax contributor.

“We fully intend to shift 25 percent of the black vote from the 2008 election by charging every voter to examine each candidate and vote for the one that supports their core belief in natural marriage.”

God Said has 22 advisory board members, including some affiliated with the Coalition of African-American Pastors, which has announced its own efforts to encourage blacks to not support Obama because of his stance on same-sex marriage.
