The parody was making fun of the L.A. Times article with that title. The song was not the source of this. The author of this piece and the Obama campaign have problems with being factual.
See my post above. The author of the L.A. Times article seems to be hiding from the very article he wrote. Ehrenstein has a very chatty blog (Fablog) in which he chats and gossips about everything EXCEPT for his own article and the national parody of it on Rush.
