As part of a long term plan to distance itself from the image of the old people's party, Republican leadership needed a more indelible reason why Dick Cheney wasn't running for President in 08 than his age. It was decided, for the good of the party, that Dick had to be involved in a scandal of some sort. Something just damaging enough to be memorable, but cause no undue hardship on VP Cheney in real world terms. A 'hunting accident' was decided on, as it allowed a deal to cut down on congressional investigations by democrats, in exchange for 3 weeks of news coverage on their favorite pet causes. From gun control, to animal rights.
