MYRTLE BEACH, South Carolina (CNN) - The Democratic presidential debate in Myrtle Beach, South Carolina has now come and gone. I must say I was pretty surprised: I knew there would be some fireworks, but I didn’t think it would become as rancorous as it did.
Hillary Clinton and Barack Obama came out swinging, and it was intense. They clearly had their zingers ready to go, and they let loose. It didn’t really matter what our questions were - whether on jobs, the economy, the sub-prime mortgage crisis, or health care - they were intent on hammering their rivals for the Democratic nomination.
This was the fourth presidential debate I have moderated during this election season. I hosted a Republican and Democratic debate back in June in New Hampshire, and a Democratic debate in November in Las Vegas. All three were much more subdued.
The shrinking field may be partly responsible for the new combative tone. When there are eight candidates fighting for time, it's tough for the candidates to go after each other. It's a lot easier when there are only three of them left standing.
Another factor: as the contest gets into the final rounds, the stakes become ever higher.
I made a deliberate decision last night to try to speak as little as possible. This was a debate, and I wanted the candidates to debate the issues, and let them go back and forth - much easier to do now that there are just three candidates left, as opposed to nearly three times as many.
During those early debates, some criticized me for interfering too much - either by interrupting the candidates and forcing them to wrap up their thoughts, or by moving on to the next question too quickly. “Why didn’t you just let them debate?” some of my critics asked. Following this most recent debate, some of my critics complained that I didn’t adequately control the two-hour session.
I certainly understand both criticisms. But I don’t agree with them.
As riveting as the back-and-forth might be, it wasn't the point of the event: I hope the people watching Monday night came away from this debate in South Carolina with a better understanding where the candidates stand on key issues.
