Liberals are up in arms, some suggesting that it’s racist (“The only thing missing is a noose”).

Such a silly reaction. There’s nothing racist at all about it.
In any case, where were they when George W Bush was done up the same way?

No, the only problem we have with Obama-Joker is that Heath Ledger’s character wasn’t really a socialist at all. He was a nihilist and the worst kind of anarchist. We are pretty sure Obama believes in something and it’s certainly not chaos. (However, we are pretty sure that the effects of his policies, like the health care thing, would absolutely result in chaos). No, a better spoof might have been something closer to Karl Marx.
