CNN reports that Benazir Bhutto was to give U.S. officials a “secret” document on the day she was killed. The document details measures by which Pakistan’s intelligence services would allegedly rig the elections. Bhutto intended to give the dossier first to Sen. Arlen Specter then to presidential candidates Hillary Clinton and Barack Obama.

The choice of these American politicians is interesting. It suggests that Bhutto believed they would be more effective than elements in the Bush administration. Specter, who was in Islamabad ready to visit Bhutto later Thursday evening, often diverges with the Bush administration despite being a Republican. Clinton and Obama are leading Democratic contenders who would relish an opportunity to throw a blow at the Bush administration’s foreign policy. Pakistan provides such an opportunity given the perceived success of the Iraq surge and its integrality to the Afghanistan problem — the primordial post-9/11 U.S. national security issue.
