From The Guardian:
An offensive, racially tinged song entitled Barack the Magic Negro has become an issue in the battle for the leadership of the Republican party.
The song was included in a CD distributed by Chip Saltman, who is seeking to be elected the next party chairman.
Saltman, former campaign manager for Mike Huckabee, the former Arkansas governor who fought unsuccessfully for the Republican presidential nomination this year, sent out the CD as a Christmas present to party members. It is a compilation of songs critical of liberals entitled We Hate the US.
He defended his move, saying that anyone listening to it would know it was intended to be light-hearted and satirical, and the row had been created by the liberal media.
The racist dogwhistle has been replaced by an airhorn, as my friend mattt put it.
