NEVER count the Clintons out of anything. You should know that by now. They almost always seem to get what they want. The loss of the Democrat Nomination is about the only exception. In my opinion, there are alot more qualified people in Gov't that would make a much better Sec of State than a Clinton, people who have spent their life in Diplomacy, which leads me to believe that it is Hillary who wants the position. Not BHO who originally thought of using her.
And you too can bet your bottom dollar if a Clinton, or both Clintons want a position of the Supreme Court, they will get it/them, regardless of their current position. I believe the Clintons still have not gotten it through their heads that Hillary won't be President.
It is not unusual to have an ex-president sit as a Justice. It has been done in the past.
You don't have to be a fan of the Clintons, but you got to be a realist. They are a wart on the nose of this country that just won't go away fast enough.
