Yea...I thought of that too but thoughts of Pelosi next in Line makes me shudder and throw up. We oddly need Biden in the fray.
You guys are wrong, if the VP dies the President appoints another one. The only way Pelosi would move up would be if the President and VP died together, as in a plane crash or something similar. President dies, VP moves into President slot and appoints a VP.
He functions as a sandbag.
