The biggest loser here was CNN, when the Republican contenders, in an almost concerted effort, took control of the debate AWAY from Jake Tapper, and rendered Hugh Hewitt and Dana Bash virtually impotent. The sharpest shots came from Chris Christie, and John Kasich was almost as pointed in his criticism of the moderator and panel.
The Donald was pretty much in bob and weave mode, and to his credit, managed to avoid any lasting damage. His overall lead was whittled down a little, but not to the point of crash-and-burn.
Yet.
CNN got high ratings- they must really be upset about that.
