Earlier in the day, McCain had mocked Obama for apparently not realizing Al Qaeda is in Iraq. Obama countered, saying that Al Qaeda wouldn't be in Iraq, had it not been for Bush and McCain deciding to attack Iraq.

Give McCain credit for taking the fight to Obama, even before Obama has vanquished Hillary ... But give Obama credit for quickly responding to McCain.
