Voters also are finally realizing they really want to know what “change” is. Is it 73 cents more in your pocket, or does it have an economic-stability package attached to it?

Obama came out of Pennsylvania looking like an elitist who can't live up to his rhetoric of bringing people together; he never showed the compassion for policy solutions that Hillary demonstrated.

U.S. Rep. Mike Doyle, a Western Pennsylvania superdelegate who has not committed to either candidate, says that’s a problem. “Obama needs to demonstrate that he can connect with blue-collar working-class people,” the Forest Hills Democrat said. “Up to this point, I don’t think he has shown that.”

As reported many times over, many Democrats, inside the Washington Beltway or in the Heartland, hope for an Obama-Clinton ticket. Brokering that deal may prove harder than herding cats; right now, ending the Cold War seemed a lot easier.

Yet to win in the fall, Obama needs Clinton more than Clinton needs him.

In the 1976 presidential campaign, Gerald Ford blamed Ronald Reagan for his loss to Jimmy Carter because Reagan did not campaign for Ford in Southern Ohio and Western Pennsylvania. Ford felt Reagan could have made the difference among what came to be known as Reagan Democrats, the same voters with whom Obama cannot connect.

Obama will need Clinton to do the same thing -- that is, if he ever herds the cats that he needs to close the deal and win the nomination.
