As chair of the Indian Affairs Committee in the Senate, McCain started an investigation of Jack Abramoff's exploitation of the tribes he represented as a lobbyist. He subpoeaed 750,000 pages of documents from Abramoff's employers, which likely hold information on all of Abramoff's dealings and contacts. But then McCain slowed down the investigation before the 2004 election and finally came out with a report that never went much of anywhere. More importantly, he has put a hold on the vast majority of the 750,000 pages so that they cannot be made public without consent of both parties. So he has played a crucial part in protecting the Bush administration and its powerful allies in the right wing, ensuring Bush's reelection in 2004 and corruption for another four years. (Recall that these are the same people who so shamefully used dirty politics to defeat him in the 2000 primary.) By showing himself to be a team player (or engaging in some brilliant blackmail) he has fully earned the nomination this time around.
