After Simi Valley

This struck me as McCain's worst performance of the campaign. He seemed - understandably - exhausted. He kept pushing some untruths about Romney's position on Iraq. He seemed vague and unfocused on the economy. He was also more aggressive in swiping at Romney who was more civil and more engaging than I have seen so far. No, I still favor McCain on the issues - and on character. But either his relief at having this almost in the bag affected him, or he is showing his age. The latter is worrying - especially against Obama.
