Tom Tomorrow's "This Modern World" is my favorite political comic. He's liberal. And it's better for me to read his comic and laugh smugly than bash my head into a wall over conservative hypocrisy. Here's his latest winner over at Salon.com.
Not that you asked, but my other favorite comics are Doonesbury, Pearls Before Swine, Monte, and Get Fuzzy. Hard to imagine starting the day without them. Well, them and a frappé.
