There was a question regarding the role of the VP.
From Wiki:
The VP is President of the Senate and is there as a voter in deadlock. He or she may be assigned additional duties by the President but, as the Constitution assigns no executive powers to the Vice President, in performing such duties he or she acts only as an agent of the president. They are first person in the presidential line of succession, becoming the new President of the United States upon the death, resignation, or removal of the President, serving out the balance of that presidential term no matter how much or little time remains in it.
IMO:
History may view Cheney as the most powerful VP and he has redefined the role for future elections and duties.
Many VPs, former Presidents and 1st Ladies represent US personal relations throughout the world. Our Founding Father were very smart and would not have placed such an office for no reason or without a strong role in government. Many VPs have used the service to grow into Presidents are at least run for nomination. So just note that not any bum can fill the shoes of the VP.
