Obama's Iowa momentum has proven too much for Hillary Clinton's campaign team to fight off. With multiple polls in New Hampshire showing a double digit lead for Obama, it looks like there is no chance that Clinton will be the Comeback Kid in Tuesday's primary. Depending on turn out, even a third place finish behind John Edwards is possible.

The relevant question now is whether Hillary has any hope of winning the nomination? The key indicator to watch post-New Hampshire will be Clinton's national poll numbers. If her once 25 point lead in national surveys falls to close to a dead heat or worse, expect major donor and VIP defections. The media will amplify her woes with a postmortem narrative on how her campaign has spiraled out of control.
