"I just wish we had ten days instead of five"

Those words, spoken by Bill Clinton, sum up the enormous challenge facing Hillary Clinton as she tries to halt Barack Obama's Iowa momentum in New Hampshire. Five days is a blink of an eye; ten days a languorous stroll by comparison. She needs to change the narrative, give voters in New Hampshire a reason to doubt the wisdom of giving the Democratic nomination to someone so relatively untested as Obama. But this will be hard to do. Obama is riding a wave right now, and his message -- of hope and change and a new kind of politics -- suits the independent-minded New Hampshire voter. Tomorrow night's debate might be her last, best shot.
