But Cameron isn't running for President, John Kerry is.
You are missing the point. Try to think about this story from a left-wing POV, and it will make more sense. Does the left really want a guy supported extensively by a group (law firm of Cameron) which has such strong Israeli business (incl. military cos.) ties? If the left is complaining about Bush being captive to Israeli interests, wait till they hear about this. Kapish?
