Trump nabs 31 percent support in the survey released Monday evening, down 2 points from the same poll conducted last week but inside its margin of error.
Sen. Marco RubioMarco Antonio RubioRubio: Kaepernick deserves to be in the NFL Congress — when considering women’s health, don’t forget about lung cancer Anti-Maduro Venezuelans not unlike anti-Castro Cubans of yore MORE (Fla.) takes 17 percent in the survey, which was conducted Thursday through Monday and included the Republican debate over the weekend. Rubio, who emerged as an establishment favorite from last week's Iowa caucus, struggled in the face of a barrage of attacks from rival New Jersey Gov. Chris Christie in that debate.

CNN said that it couldn't produce a separate estimate of support due to a small post-debate sample size, but reported that interviews in the two days after the Saturday debate "found no drop in support for Rubio" and instead "a slimmer margin between Trump and Rubio."

The survey of 362 likely GOP primary voters has a margin of error of 5.2 points.
