It all started when the best question of the night came from Facebook: A student from Georgia Tech called Donald Trump on his suggestion that he would kill family members of ISIS in order to deter terrorists from attacking us. "So my question is: How does intentionally killing innocent civilians set us apart from ISIS?"

No surprise here, Trump doubled down: "I would be very very firm with families. And frankly, that will make people think. Because they may not care much about their lives, but they do care, believe it or not, about their family's lives."

And ... you guessed it: the audience broke into applause.

With the help of an almost 2-1 advantage among women, Hillary Clinton leads Bernie Sanders 51 - 40 percent among Iowa likely Democratic Caucus participants, according to a Quinnipiac University poll released Tuesday.

Martin O’Malley has six percent with three percent undecided. This compares to the results of a November 25th survey by Quinnipiac showing Clinton over Sanders 51 - 42 percent.
