The chairman of the Republican National Committee said Saturday he was "shocked and appalled" that one of his potential successors had sent committee members a CD this Christmas featuring a 2007 parody song called "Barack the Magic Negro." In spite of RNC Chairman Robert M. "Mike" Duncan's sharply negative reaction, former Tennessee Republican leader Chip Saltsman said that party leaders should stand up to criticism over distributing a CD with the song. He earlier defended the tune as one of several "lighthearted political parodies" that have aired on Rush Limbaugh's radio show. Saltsman, who managed former Arkansas Gov. Mike Huckabee's presidential campaign, is seeking the RNC chairmanship. During the presidential campaign, Republican officials denounced efforts by those in the party who criticized or mocked Democratic nominee Barack Obama along racial lines. Obama was vying to be the nation's first black president. A spokesman for Obama, now the president-elect, declined to comment on the matter.
