"Which ever candidate receives the Democrat nomination, the other team will feel cheated. "
If Obama wins as expected, there is no metric upon which Clinton supporters can feel "cheated." He will win regular delegates, superdelegates, states and popular vote. Even the most hardcore Hillary partisan will have to struggle mightily to make a case for "cheated."
Hillary supporters will feel dejected, and they will be frustrated, because they won't feel that the best candidate won. However, it will be much easier to get most of them back in the fold than it will to get Obama supporters if Hillary were to do the impossible & get the supers to give her the nod despite losing every metric.
