Ohio Gov. John Kasich (R) places fifth with 8.5 percent support, followed by retired neurosurgeon Ben Carson with 5 percent support.

Eleven percent of respondents remain undecided before the state's Feb. 20 primary.

Trump leads among Republicans of all ideological stripes, winning pluralities of self-identified conservatives, moderates, independents and libertarians.

The South Carolina House Republican Caucus poll surveyed 1,200 likely Republican primary voters from Feb. 11 – 12.
