When it became clear that in order to maintain my integrity and to get the right message [across] I had to publicly disagree with him, he did things  or allowed things to happen  that were terrible, he said. The presidents campaign, on the other hand, made clear it wasnt interested in reciprocating such gestures of fellow feeling. As The Times editorial board wrote in its endorsement of Mr. Biden on Tuesday, his vow to restore the soul of America is core to his appeal. I didnt fixate on that, but it was in the back of my mind because I had to be out there, he said. But in the final month of the presidential race, could his commitment to the rhetorical high road end up costing him?
