Of course Biden is under lock and key.

What with that last effluvium he said about "Mark my words, there will be a monster crisis...etc etc etc..."...the O campaign simply doesn't want Biden to make not just gaffes, but make crap up to lose by 10 votes.

Biden was chosen to be the VP because all of the other more credible candidates simply didn't want to be O's VP. In fact, I had read that Biden at 65 was contemplating retiring from the Senate and that O simply grasped him for VP because he was the last man standing...
