I did not know that. Now I think I know why he studies remarks from his sometimes out-of-control adversaries; and subsequently calmly responding. My wife and I like and respect Charles Krauthhammer a lot.
I'm a big Krauthhammer fan. He has a great mind. Just chews up liberal arguments like they were nothing more than hot gas.
While I don't always agree with Krauthammer it's easy to continue to respect him and his opinions.
