Trump on debate demands; Paul - too early to give up; Clinton on immigration
What the 2016 presidential candidates are saying:
Donald Trump: Debate demands
"I want a room. I want a podium, and let's get going because I don't really care that much."
Rand Paul: "too early to give up"
"We think we're underrepresented in some of the poll numbers because our strength is among the youth....If you combine youth vote, independent vote, and liberty or Libertarian wing of the Republican party, I think there is a winning coalition. So, we are very well-organized in Iowa and New Hampshire. We're gonna surprise a lot of people. The polls are still so early. Most all of these polls, they won't tell you this, but two thirds of the people being polled in every poll are still undecided. So we think it is too early to give up on anything or make any decisions." -- interviewed by Fox News
Hillary Clinton: Our immigrant tradition
"On the Republican side, even people like Senator Rubio, who used to be for comprehensive immigration reform now, are against it because of the pressures within the Republican party. So I think we in our own country have to be honest about what we're going to do to continue our immigrant tradition. To continue our ability to welcome people and to do it in a sensible way." -- at a town hall in Coralville, Iowa
