Just my opinion without taking time to think about it...
Carly did well, she had her moments. Rand, Huck, and Rubio also each had their moments in different ways for different reasons.
Walker did too, but even when he is doing well he fails to capture your attention.
They did what they could to freeze Cruz out, but when he got the chance to speak he did well. But they gave him as little time as possible. There were others who were given little time but seized it.
Carson is a nice guy but is a bit fumbly.
Kasich excites no interest. Nor does Bush.
Trump was the target for almost everyone and took a rather constant pounding. All he had to do was survive it, and I think he did. I don’t know that he had any “moments” but I don’t think he had to. Some of the others did, and they needed to just to stay in the game.
I’ll predict that the press will be pushing Rubio and Fiorina after tonight. Trump will continue to lead. Cruz will hang on because he believes.
Kasich reminds me of my inebriated Uncle Baxter, who is in a “Gollum/Smeagle” conflict battle between his right side vs. left side, exhibiting jittery motor skills as a result. Then, sometimes he is thrusting outward on tippy-toes from one side only, his left arm limp at his side.
What is it with his constantly puckering lower lip, like he is trying to keep his dentures from popping out. He just looks like he is marginally able enough to keep from drooling out the side of his mouth.
