Obama also picked up an important new endorsement from Toni Morrison who famously called Bill Clinton the "first black president" in 1998. After Clinton disgraced himself with his racial jibes in South Carolina, Morrison took up her pen to write a personal  letter to Obama that’s worth quoting: "In addition to keen intelligence, integrity and a rare authenticity, you exhibit something that has nothing to do with age, experience, race or gender and something I don't see in other candidates

"That something is a creative imagination which coupled with brilliance equals wisdom. It is too bad if we associate it only with gray hair and old age. Or if we call searing vision naivete. Or if we believe cunning is insight. Or if we settle for finessing cures tailored for each ravaged tree in the forest while ignoring the poisonous landscape that feeds and surrounds it. Wisdom is a gift; you can't train for it, inherit it, learn it in a class, or earn it in the workplace - that access can foster the acquisition of knowledge, but not wisdom."

When Obama takes to the stage at American University he will be flanked by Senator Teddy Kennedy who spurned appeals from the Clintons, as well as Caroline Kennedy, daughter of JFK. The New York Times tells us that Teddy Kennedy had a blazing row with Bill Clinton for his misleading statements about Obama. He called Bill again on Sunday – not Candidate Hillary - to give him the bad news about today’s event.

Obama’s speech could be a big one and I expect him to echo JFK seminal "World Peace" speech of 1963 when he made the, for its time, audacious suggestion that a Pax Americana must not be enforced on the world by American might.

Here’s what JFK said way back then: "I am talking about genuine peace, the kind of peace that makes life on earth worth living, the kind that enables men and nations to grow and to hope and to build a better life for their children - not merely peace for Americans but peace for all men and women - not merely peace in our time but peace for all time. I speak of peace because of the new face of war... Our problems are man-made - therefore, they can be solved by man. And man can be as big as he wants. No problem of human destiny is beyond human beings. Man's reason and spirit have often solved the seemingly unsolvable - and we believe they can do it again."

All this has obvious echoes in the Obama message, that America should be strong militarily but not get sucked into "dumb wars", as it did in Iraq. Lets watch how it goes...
