It would be hard to overstate the significance of Barack Obama's blunder. As a certain junior senator from New York said during the primary season, while John McCain has obviously passed the Commander-in-Chief threshold, it's not clear Obama has.

The McCain camp has wasted no time in weighing in.  In a conference call yesterday, former CIA director James Woolsey said Obama's advocacy of giving terrorists access to U.S. courts was an "extremely dangerous and an extremely naive approach to terrorism."
