Twenty-one percent of registered Republicans surveyed said they would vote for Sutton, and he leads Noem among unaffiliated voters by 19 points.

"[Sutton] is competitive with Noem because voters know and like him, and he takes a lead in polling when voters hear profile information about both candidates to simulate voters getting to know them better," the polling firm writes.

Sutton has a 6 point lead when voters hear information about both candidates, according to the poll.
