After Rubio in third, Ben Carson comes in fourth, with 5.7 percent support. No other Republican draws more than 5 percent support.

The poll was conducted Feb. 6–9, largely after Rubio’s shaky performance in Saturday night’s GOP debate but before Trump’s resounding victory in Tuesday's New Hampshire primary and a stronger-than-expected showing from John Kasich.

“Early on, Trump’s been able to channel the anger and frustration felt among Republicans toward President Obama, but anger and frustration can only take you so far in a presidential race,” said Bill Shapard, founder of the SoonerPoll.
