How does Ted Rall get away with this con?

It would seem that an artist wouldn't need to use so many captions to explain his drawings, or that an essayist wouldn't have to use crude drawings. All his people look exactly like each other. When he tries to draw one who doesn't, it turns out looking like it was drawn by a 10 year old. I first saw his garbage in a periodical called Funny Times. I dropped the subscription because it wasn't funny. None of its political cartoons were funny and most of the drawings in it were liberal and about as funny as Rall.
