Once the public loses confidence in a president's leadership at a time of war, once they don't trust him anymore, once his credibility is sharply diminished, how does he get it back?

Success in past U.S. conflicts has not been strictly the result of military leadership but rather the judgment of the president in choosing generals and setting broad strategy.

As someone who has more than a passing acquaintance with most of the 20th century presidents, I have often thought that their accomplishments have little staying power in shaping popular views of their leadership.

Whatever the long-term legal prospects for same-sex marriage, President Obama's willingness to put the matter front and center in an election year can at least make him a candidate for inclusion in Kennedy's Profiles in Courage.

John Kennedy had so many different medical problems that began when he was a boy. He started out with intestinal problems... spastic colitis.

Concealing one's true medical condition from the voting public is a time-honored tradition of the American presidency.
