Couple of comments
Looks like they threw away the rulebook:
Plenty of split screens - CSPAN did nothing but splits.
Plenty of 30 second continuances.
Lehrer asked non-scripted question to clarify points.
Failed predictions:
Bush broke the rules first.
Kerry kept to his time.
Great comment/cheap shot by Andrew Sullivan (can't imagine why his quote quota has gone down here lately ;-) )
"No president who has presided over Abu Ghraib should ever say he wants to put anyone on a leash. "
