Good satire is about attacking the powerful, and that tends to be more the purview of the left. Maybe there's something about the conservative mindset that confuses mean-spirited name-calling and insults with actual humor.

My cartoons appear in newspapers, which are full of words, but there's something about having it in this little box that confounds people's expectations.

I don't think that what I'm doing [political cartooning] is necessarily left versus right. What I'm addressing is top versus bottom. If I'm not spending a lot of time making fun of the more extreme elements of the Green Party, it's because what I do is to critique power.

To keep doing this job [draw political cartoons] week after week, I think you have to want to change the world, while understanding that you can't. You have to hold both of those contradictory ideas simultaneously.
