Former New Jersey Gov. Chris Christie trails further behind at 5 percent, followed by entrepreneur Vivek Ramaswamy at 4 percent. North Dakota Gov. Doug Burgum is at 2 percent and former Texas Rep. Will Hurd has 1 percent.

Businessperson Ryan Binkley, conservative radio host Larry Elder, former Arkansas Gov. Asa Hutchinson, businessperson Perry Johnson and Miami Mayor Francis Suarez all sit below 1 percent in the new poll.

Twenty percent of those polled chose DeSantis as their No. 2 pick, making him the top second-choice candidate in the poll. Scott is in second with 15 percent and Ramaswamy with 12 percent.

Still, the contest may be “closer than it may first seem,” said J. Ann Selzer, president of Selzer & Co., the firm that conducted the poll. Sixty-three percent of respondents said they support Trump as their first or second choice in the caucuses while the 61 percent of those surveyed said the same for DeSantis.

The poll of 406 likely Republican caucus-goers was conducted Aug. 13-17 in English and by telephone. The survey has a margin of error of plus-or-minus 4.9 percentage points.
