Adam Nagourney - On the Campaign - Election 2008 - Politics - New York Times

"Eliot Spitzer, the former New York governor, certainly wasn’t thinking about presidential politics when he proposed in New York that illegal immigrants be granted driver’s licenses. But when Mrs. Clinton was asked about his proposal at a debate last year, she gave an equivocal answer — make that answers, since she seemed in the course of the debate to say both that she opposed it and that she supported it — in what may well have been the single most politically damaging moment of her campaign. It encapsulated the image of Mrs. Clinton as cautious, calculating and disingenuous. That night is arguably when the descent began."
