You two kids! Break it up!

I think what Edwards is trying to do here is play the grownup:

"The last thing we need is two presidential candidates fighting with each other, instead of fighting for the change we need in America," Edwards said. "And, man, do we need change in the worst possible way."...

An Obama spokeswoman disputed Edwards' comments about the Clinton-Obama spat.

"This is a substantive and important debate people want to hear about, whether we are going to turn the page on the Bush-Cheney foreign policy, which has damaged our national security and America's standing in the world," Leslie Miller said.

That is: We're not kids. We're the adults!
