The poll, however, also shows that the race is in flux: 55 percent of GOP primary voters say they could change their mind before February’s balloting.  Less than half, 44 percent, feel certain of their choice.   

When asked about their second choice candidate, GOP primary voters put Carson at the top of the list at 16 percent.  Rubio is close behind at 13 percent and Trump at 11 percent.

When first and second-choice preferences are combined, Trump (38 percent) and Rubio (26 percent) are still at the top.  However, Carson (25 percent) moves above Cruz (20 percent) and Bush (16 percent).

The favorites among those NH GOP primary voters who identify as “very” conservative are Cruz (27 percent), Trump (26 percent), Carson (13 percent) and Rubio (13 percent).
