Poll: Trump losing head-to-head against Cruz, Rubio

Donald Trump remains atop a new Economist/YouGov national survey, but he loses hypothetical head-to-head match-ups against Sens.Ted Cruz of Texas and Marco Rubio of Florida. The online survey was conducted before Trump proposed banning Muslims from entering the United States.

Trump leads the Republican field with the support of 35 percent of those surveyed, followed by Rubio at 18 percentage points and Cruz at 13 points.

But Cruz and Rubio each lead Trump by six percentage points, 53-47, when they face Trump one-on-one. Neither Cruz nor Rubio led Trump when YouGov last surveyed the GOP race in November. When Cruz and Rubio are pitted against one another, Cruz emerges victorious by eight percentage points, 54-46.

"The good news for Cruz and Rubio (and the bad news for Carson) may reflect the impact of the terrorist attacks in Paris and San Bernardino," wrote Kathy Frankovic for YouGov. "Now Rubio has become the Republicans' best-liked candidate: 71 percent of Republicans now have a favorable view of Rubio, up six points in the last two weeks. Trump, Carson and Cruz are seen favorably by fewer, though more than 60 percent of Republicans like each of them. For both Trump and Carson, this week represents a drop in favorability from late November."
