"Those files -- that's the mother lode of opposition research," said Ray McNally, a Republican political consultant in Sacramento. "Opposition researchers would be very hungry to see what's there." Robert Shrum, senior political strategist in Democratic Sen. John F. Kerry's 2004 presidential campaign, said: "In 2 million pieces of paper, would opposition researchers hope to find one where she wrote a memo saying, 'I wish I'd never gotten involved in healthcare?' Sure. That's what they'd love to find."

What records that have been made public offer tantalizing details about [Hillary Rodham Clinton]'s White House years. One memo reveals details about the "war room" for the healthcare plan. Aides wrote of the need for secrecy, but also presented Hillary Clinton with arguments she could make that the process of drawing up a healthcare plan was "the most open in the history of the federal government."
