Reuters ASPEN, Colo.–On the main stage Wednesday at the Aspen Ideas Festival, Walter Isaacson, president and CEO of the Aspen Institute, echoed a criticism of President Obama that a number of his supporters have voiced. "Some of us feel that there was an opportunity for this president to really deal passionately, vocally, and without putting a muffled hand in front of the microphone, on the issue of race," he said.
