My theory is...
Clinton & Gore were so arrogant that they thought the 2000 election was sewn up. When they lost they pushed the Fla recount knowing in the end it would go no-where.
Remember the Wall memo that Gorelic (I am not sure how she spells it.) That was to protect the Clintons from the CIA and the like from sharing data on the Chinese funny money rolling into their coffers.
In a panic they found out about "Able Danger" worried it might contain evidence to expose them and ordered the purge. The Atta stuff was not the reason for the purge just a bonus.
Enter 9-11 and the "Commission another panic alarm goes off again as someone remembers a breifing on Atta and his cell.
Sandy Burglar goes and steals and destroys the documents relating to those breifings.
Jamie G's role on the commission was to find out what was going on behind closed doors and get that info to the Clintons so they could arrange the desposal of any incriminating documents.
Yes. They thought it was going to be a landslide. When it turned out Bush won, they started to scramble. They destroyed the WH computers and the files were torn apart. The WH was trashed.
Nice.
