Pimp. Barack Obama makes him purr.
Also, you'll note that while he is clearly not happy, he is also clearly not as unhappy as he's been in other get-ups I've forced him to wear. This, by the way, is an Obama T-shirt I bought online that is about the most ill-fitted thing I've ever owned. I would have junked it by now, but it's just so damn cute. I mean, look at it... Baa-rock.
Besides, Pimp is an Obama Cat and he makes it look good. :)
