Mike Huckabee's victory in Iowa’s GOP caucus can be largely attributed to his overwhelming support among evangelical voters and women, our entrance polling shows.
Evangelicals constituted the majority of Republican caucus goers (60 percent), and our entrance polling shows Huckabee won 45 percent of that group. Mitt Romney, who has heavily courted social conservatives only drew 19 percent of those voters.
Huckabee also overwhelmingly won the female vote, picking up close to 45 percent of women, to only 23 percent for Romney.
