ABC News: In his 60 Minutes interview set to air Sunday, President Obama admits some failures in his leadership. In an excerpt from the interview that aired on the CBS News Early Show, correspondent Steve Kroft said: "There is this feeling, Particularly among people who are among your most ardent supporters, who feel a little disappointed that they think that you've lost your mojo. That you've lost your ability, that touch you had during the campaign, to inspire and lead. Everybody in Washington writes about a sort of aloofness that you have. How do you respond to that?"
