You are making the mistake of assuming that the members of the press actually are honest and GIVE a d@^n. They don't care that Whittington got shot (in fact, they wish he would die already to give them a better story).
It doesn't matter what VP Cheney does or doesn't do -- if they don't have anything to attack him on, they'll make something up.
Actually, I hope they DO continue to bring it up. A LOT of Americans are hunters or at least have been hunting. I had some guy tell me the other night it's only 4% of the population but that's based on the number of licenses that are issued. I only get a license when I'm planning a hunting trip. Haven't gone for years, but I know full well what they are like, what happens when you go, etc. A very LARGE portion of the population is just like me.
So, the more dems bring it up, the more elitist they look and the more they let the people know just how far they are removed from everyday life in this country.
