I don’t think your view is a stretch at all. My point is that you are inserting your own set of biases into the cartoon:
1) You assume the cops are white and that that makes a difference.
2) You assume that chimpanzee = commentary on race instead of intellect.
3) You assume the chimpanzee is Obama.
4) You assume that Obama’s father’s lineage makes up his entire racial identity. If they really wanted to make fun of black people, they would have shown something half Caucasian and half chimp.
You said he doesn’t look black or Asian. Tiger Woods doesn’t look Asian either, but he is. Steve Byrne doesn’t look Irish, but he is. Duane Johnson and Lisa Bonet don’t look black, but they are. Lenny Kravitz and his daughter don’t look Jewish, but they are. Halle Berry and Obama don’t look Caucasian, but they are.
And the fact that I would not have made the connection otherwise is exactly why it is clever. They took two entirely unrelated events and put them together in a creative way to make an accurate political statement about the absurdity of the stimulus package.
