The Republican candidates for president debated for the second time last night, and the popular commentary is below.

Rand Paul attacked Donald Trump, the most common target of the night, in part for his comment about Carly Fiorina's appearance:

"I kind of have to laugh. I'm very concerned about having him in charge of the nuclear weapons because I think his visceral response to attack people on their appearance - short, tall, fat, ugly - my goodness, that happened in junior high. Are we not way above that? Would we not all be worried to have someone like that in charge of the nuclear arsenal?"

Trump shot back, "I never attacked him on his looks, and believe me, there is plenty of subject matter right there."

Fiorina handled the situation well, and several analysts applaud her "breakout performance" throughout the debate.

She was, once, put in her place by Chris Christie: "You interrupt everyone else on this stage. You're not going to interrupt me."
