Nate Silver: “Rubio has gained about 6 percentage points in the New Hampshire polls, while Donald Trump has lost 2 points (although Trump remains the favorite here). There’s still a tiny bit of pre-Iowa data in the polling average, and the numbers will undoubtedly shift around a few points over the weekend. But if any candidate were emerging with massive momentum as a result of his Iowa performance, we probably would have seen it by now.”

“Cruz isn’t. In fact, his numbers haven’t really moved at all. He’s polling at 12.4 percent today, versus 12.0 percent before Iowa.”

MSNBC: “In the three months leading up to the Iowa caucus, many Republicans spent little to nothing on polling. Marco Rubio and Jeb Bush each spent just over $150,000 on campaign polls, while the two non-politicians in the race, Ben Carson and Donald Trump, declined to buy any polling research at all. The data is from the campaigns’ spending summaries for the final quarter of 2015, which are released under federal election law.”

“Ted Cruz was the only Republican who spent much on polls – over $380,000 – and his campaign threw another $3 million into separate data for ‘donor modeling.'”

First Read highlights how last night’s contentious Democratic debate ended on a positive note when both candidates were asked if they would choose each other as their running mate.

Clinton’s answer: “If I’m so fortunate as to be the nominee, the first person I would call to talk to about where we would go and how we’d get it done would be Senator Sanders.”

Sanders replied: “I agree with what the Secretary said, we shouldn’t be getting ahead of ourselves. And as I have said many times, you know, sometimes in these campaigns things get a little bit out of hand. I happen to respect the secretary very much, I hope it’s mutual. And on our worst days, I think it is fair to say we are 100 times better than any Republican candidate.”

A new Quinnipiac poll finds Donald Trump still leads the GOP presidential pack nationally with 31%, followed by Ted Cruz at 22%, Marco Rubio at 19% and Ben Carson at 9%. No other candidate above 3 percent.

In the Democratic race, Hillary Clinton barely leads Bernie Sanders, 44% to 42%.

Said pollster Tim Malloy: “Democrats nationwide are feeling the Bern as Sen. Bernie Sanders closes a 31-point gap to tie Secretary Hillary Clinton. And despite the Iowa setback, Donald Trump is way ahead of his GOP opponents.”
