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.
He's so not funny now though, I wish none of the papers wasted money on his strip. I worshipped at the altar of Bloom County up to about the release of Toons For Our Times, then he married some PETA witch and went completely bonkers lib. Mary Kay Commandoes was putrid, and it only got worse.
Ronald-Ann? EEEAARARGH!
