Yes, it sounded like his voice was almost about to break.
Whether he was sincere or not is another question.
His son recently enlisted, and I believe he quit his job to do so. His was almost 30 years old, and is certainly someone who didn't need to enlist, but started thinking about it after 9/11.
I could complain for a while about Daley, but he is not an anti-military dem.
Daley's son enlisted recently, I would imagine he was sincere.
