The chimp in the current controversial cartoon doesn't even look like a caricature of anybody. Most editorial cartoons are confusing and so I just make up my own meaning for them and since the chimp doesn't look like any famous human associated with the porkulous bill, I assumed the reader was supposed to assume that an insane chimp on the rampage literally wrote the bill.
And if I didn't know that rampaging congressmen/women/senators were far more dangerous and insane than a rampaging chimp I could easily believe it.
