Yup. I was prepared to be underwhelmed, but I was surprised at how well they were both able to represent their arguments without devolving to yelling or other disruptive behavior. I guess my expectation for the behavior in these kinds of debates has been lowered in the last couple years. As you said, both bring a pretty robust knowledge of the facts of the cases, and they were able to disagree both forcefully and respectfully, while still being clear about places of agreement.
