"Whatever authority a vice president has is derived from the president under whom he serves. There are no powers inherent in the office; they must be delegated by the president. Somehow, not only has Cheney been given vast authority by President Bush -- including, apparently, the entire intelligence portfolio -- but he also pursues his own agenda. The real question is why the president allows this to happen."
My guess is that Shrub didn't want to actually WORK. Shrub has never worked for ANYTHING. When he engaged in independent thought, he left a mess for someone competent to clean it up.
