These files will be “sanitized” of the leftist political connections throughout the Vietnam war and Reagan, but they WILL leave in some stuff about his carousing because that will divert attention FROM the political stuff.
In the movie Charlie Wilson's War, there's a scene where the CIA guy says it's great that Wilson is being investigated for cocaine use: "If you've got sex and drugs to look at on this hand, you can hide a f***ing battlecruiser behind THIS hand, and no one's going to see it." Great movie.
