Hi Mate I understand that age is an issue but have to add a great big SO WHAT!
Take any former VP and look at what "qualifications" they've had. In the event that a POTUS snuffs it during his/her term of office does not mean that all the advisers/staffers department heads and the legions of other civil servants suddenly stop functioning and descend into a state of administrative atrophy. Government goes on!
Presidents take office with absolutely no training or qualifications for the job...none! All they have proven is they can speak.... tell a good tale and survive the maelstrom of the 24 hour press corps! We have the same with our politicians... with a few exception they are functional failures in commercial life! You would not employ them!
We are taking about politicans

I think you need to take a step back and really look at the political and administrative processes under which a President and Vice President function - they do not operate in a vacuum, nor would they be permitted.
Thus, is Palin any less "qualified" to make choices than McCain?
