Presumably at some point someone will ask Joe Biden whether or not he'd run for president in 2016 if Obama were to win election and re-election. Today, Biden is 65. He'll be 73 in 2016, roughly the same age as John McCain is now. Imagine the implications if Biden pledged not to run?
Update: Commenter Lynn Dee came up with a good line:
If I'm as sharp as I am now, I'll absolutely consider it. If I've lost a step, probably not. And if I've forgotten how many houses I have, unequivocally NO.
