Enough already.
They don't call it their 'silver bullet' for nothing.
They will dig dirt on the and anything related as long as they can.
Remember, they vetted GWB's National Guard service in 2000, and they've done it twice in 2004, each time getting a good week or more of negative PR.
As long as they can keep any negative PR going on the Iraqi prison abuse scandal, tney will. And why not, the other side is staying quiet and letting them.
