One of the author's conclusions:
One thing that President Obama can learn from the fate of his predecessor’s plan for space exploration is that continued, periodic political support at the Presidential level is of great importance—or is perceived to be within the space community—because of the sentiment that the national space exploration program is a tool to be used by and within the prerogative of the executive. Should international cooperation play a greater role in American plans in the near future, engagement by the President and State Department on behalf of NASA will be quite valuable.
