Despite a successful political career that includes six statewide election victories in Massachusetts, capturing the Democratic presidential nomination and coming within a hair of winning the White House, John Kerry often seems awkward, aloof, pompous and politically tone deaf.
These traits, however, aren't inhibiting an auspicious start as a diplomat. In less than a year as secretary of state, he has rolled up more tangible accomplishments than his celebrated and cautious predecessor, Hillary Clinton, did in four.
Through persistence, energy, deep knowledge and dumb luck, he has joined with the Russians to make Syria turn over its chemical weapons, persuaded the Israelis and Palestinians to start talking, and was a central player in the interim agreement on nuclear weapons with Iran. All of these accomplishments could yet unravel, but they are substantial.
He wins praise from an illustrious Republican predecessor, George Shultz. "He is doing a terrific job," says Shultz, who served under President Ronald Reagan. "He has thought about this territory energetically and creatively for a long time."
There are caveats. Kerry's habit of periodically putting his foot in his mouth hasn't vanished. He hailed a long-term deal with Afghan President Hamid Karzai that hasn't yet materialized; his rhetoric on Syria was all over the lot; and he misspoke about leaders of Egypt's military coup.
It remains an open question whether the White House will try to rein him in. Associates say he and President Barack Obama respect each other, though accounts that they forged a close bond when Kerry helped prepare Obama for the debates against Mitt Romney during the last presidential campaign are exaggerated.
But this White House, more than any since Richard Nixon's, clings to power and authority. Even Secretary Clinton, despite her political standing, was kept on a bit of a leash.
And Susan Rice, the president's national security adviser, wanted to be secretary of state but removed herself from contention with her comments on the killing of U.S. diplomats in Libya.
