At home, Jon Stewart was poking fun at the grandiosity of the “Obama Quest” and “the Obamanauts.” He showed film clips of “our hero” in chain mail fighting off dragons and a Cyclops in his crusade to come home and rule over Dreamerica.

By happenstance, on O-Force One I raised the matter of quests and Cyclops with the candidate. Having read that he had left the trail in early June to go back to Chicago and see his daughter Malia perform in “The Odyssey” for theater class, I wondered if that rang any bells on this trip? The hero on a foreign journey, battling through obstacles to get back home, where more trouble would wait?

“The whole sort of siren thing, the Cyclops, that’s interesting,” he said.

Unlike an idol, Bobby Kennedy, Obama does not see himself in terms of Greek myth, although he did tell The Times’s Jeff Zeleny on the trip that he knew the risks of “flying too close to the sun.”

The Obamanauts were so pleased with navigating their complex thicket of global photo-ops  without even one embarrassing picture of Obama hugging an Arab  that they weren’t as wary with the press.

The senator left his briefing books behind for a rare instance of mingling with his journalism posse at a Berlin restaurant as he sipped a rare “very dry” martini with olives. (This was either because he wanted to charm the press, which, contrary to popular imagination, is not universally enchanted with him, or because he could not get ESPN in his hotel room.)
