Former President Clinton's success as hostage liberator has columnist Al Hunt wondering whether the Comeback Kid will continue to be unleashed. "Could he play a bigger, broader role as a special envoy or troubleshooter on nuclear proliferation, China or any number of other challenges? Some Clintonistas already have visions of the new senior statesman of the world," Hunt wrote. But that kind of role would seem to invite problems, given that Clinton's wife is secretary of state and the former and current presidents are hardly close. "Publicly, the president praised Clinton,” Hunt noted. “Privately, the White House downplayed the importance of Clinton's role, with a top National Security Council official trashing the former president on background."
