Barack Obama is rapidly losing support among African-American voters in North Carolina, a new poll from the Democratic-leaning Public Policy Polling shows

The poll finds that Mitt Romney would get 20% of the African-American vote if the election were held today, compared with 76% for Obama. Overall, Romney has a 48% to 46% lead on Obama in the crucial swing state. Obama received 95% of the support from African-Americans in North Carolina in the 2008 election, compared with just 5% for Republican nominee John McCain. In PPP's May 2012 poll, Obama received 87% of the African-American vote to Romney's 11%. All of Obama's numbers with African-Americans are sliding. His approval rating is down from 86% to 77%. Romney's favorability, meanwhile, has doubled from 9% to 18%. The decline in African-American support for Obama follows the general trend of voters in North Carolina.
