Is this the best they can do?

Is this latest McCain ad a joke? It tries to mock Obama for talking about a light coming down on people’s heads and giving them an epiphany to ’vote for Barack.’ The thing is, I’ve heard Obama give this little line at various campaign stops -- and he always does it in complete self-mocking jest. Can they really get mileage out of mocking Obama for something for which he’s already mocking himself?

This after the Britney-and-Paris Hilton ad. Don’t they know that Britney is a Bush fan and Paris Hilton’s parents are McCain donors?
