John McCain is losing and knows it. He feels, in fact, that he’s trapped in a kind of jail cell — a cell of ugly rhetoric and impossible taskdom, given the his poll numbers since the economic meltdown — that he can’t escape from. How do I know this? Because earlier today in Pennsylvania McCain said, “Across this country this is the agenda I have set before, my fellow prisoners.” Maybe we’re all prisoners in a mortal existential sense, but McCain was clearly revealing the Freudian undertow.
