President Obama acknowledges that he failed to sell the American people on the importance of his agenda. “We were so busy and so focused on getting a bunch of stuff done that, we stopped paying attention to the fact that leadership isn't just legislation. That it's a matter of persuading people. And giving them confidence and bringing them together. And setting a tone," Obama said in an interview with 60 Minutes set to air Sunday. "Making an argument that people can understand," Obama continued, "I think that we haven't always been successful at that. And I take personal responsibility for that.” The assessment comes after the Democrats suffered what the president called a “shellacking” in the midterm elections.
