Graham's approval rating with primary voters is at 66 percent, with 26 percent disapproving. He leads a generic "more conservative" Republican in the race by 51 to 40 percent, a big jump from the 37 to 52 percent position he was in when the pollster last checked slightly less than a year ago.

The poll of 506 Republican primary voters was conducted from Dec. 7-9 and has a margin of error of plus or minus 4.4 percentage points.
