Obama was elected in a flourish of promise that many in the African-American community believed would help not only to symbolize African-American progress since the Civil War and Civil Rights Acts but that his presidency would result in doors opening in the halls of power as had never been seen before by black America.

During the 2008 campaign, I strongly endorsed Barack Obama for president. I did so early, when many Democratic leaders - including many prominent African-American politicians - believed the safe bet was to back then-front-runner Hillary Clinton.

Since the heady days of the 2009 Inauguration, middle-class independents have grown increasingly distant from Obama. Working-class voters - always more enamored of Clinton - have grown even more wary and distrustful of the Chicagoan. Both voting blocs pose the danger of serious defection in 2012. Without their support, Obama cannot win.

Slavery is nothing to joke about. The history of this nation's involvement with slavery is nothing to pass off in a joke.
