They actually are attacking cartoonists now. I was going to put up the video of the Hannity and Colmes segment when Comcast went down. Media Matters has information here.
"Brent Bozell III, founder and president of the conservative Media Research Center, falsely claimed that "cartoons that are conservative ... never see the light of day in the Pulitzer Prize selection process."
Now, I'm against this pie-ing craze, but I wouldn't be surprised to see ol' Brent get a peach cobbler thrown his way one of these days.
