About a dozen newspapers out the 1,400 carrying Gary Trudeau's Doonesbury comic strip have objected to today's installment in which President Bush refers to his chief political advisor, Karl Rove, as 'turd blossom.'  The president's nickname for Rove, which has been widely reported, refers to a scene not uncommon in rural America, a wildflower growing out of  (or through) a cow pie.  Apparently it was the reference to a bodily function of the solid persuasion, not the political content that provoked the 10-12 newspapers to censor today's Doonesbury.
