I don't like to get too political on this blog, but I think this subject falls within the domain of my cartooning expertise rather than my political leanings.
Gawker's "Cartoon Violence" feature just posted an entry called, "World's Worst Editorial Cartoonist Shares Wonderful Colin Powell Traitor Cartoon." It's hard to argue with their conclusions:
Hey, were you wondering who the worst political cartoonist in the United States is? We have an answer! It's California-based syndicated cartoonist Gordon Campbell, who took a break from his recent joke-free cartoons about how we are now a nation of communists because of the bailout bill to draw a very special cartoon in which he just colored noted traitor Benedict Arnold black and called him Colin Powell. That is the whole of this cartoon, a portrait of the man who betrayed George Washington and this young nation, in blackface, with white flags, and the utterly insane caption "Benedict Powell... Race Patriot."
(Now, for a GOOD Benedict Arnold cartoon, count on Kate Beaton. Click for larger version.)
PS—Also liked Gawker's piece on the second-worst cartoonist, the New York Post's Sean Delonas: "The Joke So Ill-Advised, Sean Delonas Made It Multiple Times" Awww. I miss the Post. They so crazy.
