While that cry served her well in New Hampshire, in the long run that kind of thing provokes voter fatigue.

And what about John Edwards? Nomentum, par excellence.

No doubt he is hoping Clinton and Obama spontaneously combust, politically speaking. They won’t, however, and sometime between South Carolina and Super Tuesday will be his last stand.

Clearly, Edwards not only enjoys the campaign trail, he seems addicted to it. It may be time for him to go back to North Carolina and run for governor.

According to Newhouse, “Any bounce that any candidate has had going into any state has worn off. Almost as soon as they get momentum, it wears off.

“This is definitely the anti-year for momentum.”

So, here’s the best recommendation for the presidential races: Watch, but do not bet.
