The winner of the Fox "presidential primary" is Huckabee who tops the list for regular Fox viewers at 18 percent, followed by Mitt Romney at 17 percent, Palin at 13 percent and Gingrich at 13 percent. Santorum was way back at 3 percent, according to the poll conducted Feb. 18-20. The margin of error is 3 points so no one in the top four is too far apart when it comes to viewer support. Gallup defined regular viewers as those who tune in four to five times a week.
