What's also funny about this revelation is the fact that that dingbat Eleanor Clift doesn't even know Biden revealed something he shouldn't have.
So she thinks she's cleverly conveying Biden's supersnarky dig at Cheney (who is so obviously nutty), while in reality the supergenius combo of Biden and Clift are unwittingly bumbling out state secrets that expose the sitting and all future vice presidents to increased risk of terrorist attack.
So Eleanor, tell me more about how dumb Bush and Cheney are...
