Haha! Bloom County was my favorite comic strip growing up. Somehow thinking back on it now, I didn't associate it's political stance as attempting to be a parody of the PC left, but I was probably only about 10 when I was reading it, so.... maybe I missed that goal.
Bloom County's Berke Breathed is definately a lefty, even though he did take a lot of shots at lefties, but he was even more harder on conservatives.
