She abused prescription drugs, McCain has admitted to being a drinker, gambler and womanizer in his youth in his biography, Obama frequently talks about his experimentation with drugs and alcohol, I think this is a wash with all of them. Quite frankly, I think it makes all of them a little more "mortal" and like the rest of us. Remember when everyone thought the "discovery" of GWB's past DUI would do him in a few years ago. I really think that just makes them more empathetic.
Be careful. Any hint whatsoever that The Chosen One might be a mere mortal just like the rest of us is frowned upon in certain quarters. Even if he admits to human failings himself. You're not supposed to point it out.
Family values? It says nothing about family values. Cindy McCain was simply saying she was the only child born of the union between her father and mother.
