Obama’s had another advantage in these debates, one that is difficult to quantify but very real: he simply seems more comfortable, and confident, than McCain. Part of this is, sadly, attributable to the physical awkwardness imposed by McCain’s war wounds and his bouts with cancer — the restricted arm movements; the scarred, clenched jaw. But there is also a pent-up anger to McCain. He seems to be concentrating so hard on trying to stay calm that he doesn’t have much energy left over to answer questions in a free and creative way. He is not the sort of person, in the end, that you want to invite into your living room for a four-to-eight-year stay. Barack Obama is. We are witnessing something remarkable here: Obama’s race is receding as he becomes more familiar. His steadiness has trumped his skin color; he is being judged on the content of his character.
