A lot of what has gone wrong with the Bush presidency lies with they way it has been warped by his veep, Dick Cheney. Carter-administration veep, Walter Mondale, says Cheney's manipulations have been "alarming". From the Washington Post:
...it wasn't until Jimmy Carter assumed the presidency that the vice presidency took on a substantive role. Carter saw the office as an underused asset and set out to make the most of it. He gave me an office in the West Wing, unimpeded access to him and to the flow of information, and specific assignments at home and abroad. He asked me, as the only other nationally elected official, to be his adviser and partner on a range of issues.
Our relationship depended on trust, mutual respect and an acknowledgement that there was only one agenda to be served -- the president's.
Subsequent administrations followed this pattern. George H.W. Bush, Dan Quayle and Al Gore built their vice presidencies after this model, allowing for their different interests, experiences and capabilities as well as the needs of the presidents they served.
This all changed in 2001, and especially after Sept. 11, when Cheney set out to create a largely independent power center in the office of the vice president. His was an unprecedented attempt not only to shape administration policy but, alarmingly, to limit the policy options sent to the president.
Through his vast government experience, through the friends he had been able to place in key positions and through his considerable political skills, he has been increasingly able to determine the answers to questions put to the president -- because he has been able to determine the questions.
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.
Three decades ago we lived through another painful example of a White House exceeding its authority, lying to the American people, breaking the law and shrouding everything it did in secrecy. Watergate wrenched the country, and our constitutional system, like nothing before. We spent years trying to identify and absorb the lessons of this great excess. But here we are again.
