Turd Blossom

I'm really laughing my ass off. "Doonesbury" creator Gary Trudeau used an allegedly true nickname for Karl Rove in his last two strips. The nickname, being slightly off color, has caused newspapers around the country to get some complaints. A few papers have gone so far as to pull the strip or edit the final panel of today's comic to remove the 'offensive' word.

My main question is this: Are they offended by a satirical artist using the term? Or are they bothered by the fact that the President of the United States actually calls Rove, "Turd Blossom"? I hope it's the latter.
