A president who roamed across the national and world stages with an unshakable self-assurance that comforted Republicans and confounded critics since 2001 suddenly finds himself struggling to reclaim his swagger. Bush's standing with the public -- and within the Republican Party -- has been battered by a failed Social Security campaign, violence in Iraq, and most recently Hurricane Katrina. His approval ratings, 42 percent in the most recent Washington Post-ABC poll, have never been lower.

A president who normally thrives on tough talk and self-assurance finds himself at what aides privately describe as a low point in office, one that is changing the psychic and political aura of the White House, as well as its distinctive political approach.

Most of all, White House aides want to reestablish Bush's swagger -- the projection of competence and confidence in the White House that has carried the administration through tough times since the Sept. 11, 2001, attacks.

Bush likes to say his job is to make tough decisions and leave the hand-wringing for historians and pundits. He almost never entertains public doubt, which is part of the White House design to build a more powerful presidency. The term "strong leader" appears in at least 98 speeches he has given during his White House years, according to a database search, and was the subtext of his 2004 campaign strategy. He favors provocative language, declaring that he wanted Osama bin Laden "dead or alive" and taunting Iraqi insurgents to "bring 'em on."
