Saltsman, who managed former Arkansas Gov. Mike Huckabee's presidential campaign, is seeking the RNC chairmanship. A spokesman for President-elect Barack Obama, Ben LaBolt, declined to comment on the matter.
The ditty by conservative comedian Paul Shanklin refers to a March 2007 opinion piece in the Los Angeles Times by David Ehrenstein headlined "Obama the 'Magic Negro."' In the article, Ehrenstein argued that voting for Obama helped white voters alleviate guilt over racial wrongs in the past.
Shanklin's parody is sung to the music of "Puff, the Magic Dragon." Among other Shanklin tunes on the 41-track CD that Saltsman sent with a Christmas message: "I Can Talk Like a Coal Miner's Daughter," "Love Client #9" and "Down on the Farm with Al Gore."
"The 2008 election was a wake-up call for Republicans to reach out and bring more people into our party," Duncan said in a statement. "I am shocked and appalled that anyone would think this is appropriate as it clearly does not move us in the right direction."
In a statement that followed Duncan's, Saltsman said: "Liberal Democrats and their allies in the media didn't utter a word about David Ehrenstein's irresponsible column in the Los Angeles Times last March. But now, of course, they're shocked and appalled by its parody on the 'Rush Limbaugh Show.'
"I firmly believe that we must welcome all Americans into our party and that the road to Republican resurgence begins with unity, not division. But I know that our party leaders should stand up against the media's double standards and refuse to pander to their desire for scandal," he said.
The Hill, a Capitol Hill newspaper that published a story about the CD on Friday, reported that Saltsman said members of the GOP committee have "the good humor and good sense" to see Shanklin's tunes as "lighthearted political parodies."
