Former New York City mayor Rudy Giuliani still leads the Republican field, but former Arkansas Gov. Mike Huckabee has more than tripled his support in a month, according to an American Research Group poll released Monday.
Huckabee jumped to 18 percent from 5 percent since the October poll, placing him third among the eight-man field. A Clemson University Palmetto poll released last week showed similar growth in Huckabee’s South Carolina support, while showing Giuliani had fallen from the front of the GOP field.
