Democratic governor candidate Billie Sutton released a poll Thursday that shows him with a 3-point lead over Republican opponent Kristi Noem.
The poll, administered by ALG Research, says Sutton is leading Congresswoman Noem 45 percent to 42 percent with 10 percent undecided. Libertarian candidate Kurt Evans garnered 3 percent in the survey.
The poll surveyed 500 likely South Dakota voters via telephone between Sept. 20 and Sept. 24 according to the polling memo. The margin of error is 4.4 percent.
The Noem campaign attacked the poll as partisan.
Surveys from this same firm showed Sutton trailing Noem by 4 points in July and down 13 points in October 2017.
ALG said that Sutton's "impressive crossover appeal" and high favorability rating has helped him close the gap with Noem and overtake her.
"We’ve felt the energy in this race as Republicans, Independents, and Democrats alike tell me they’re frustrated with the stale and complacent culture in state government and are ready to end politics as usual," Sutton said in a press release.
The poll says nearly three times as many voters are unfavorable to Noem as Sutton. Registered Republicans who took the poll had a higher unfavorable rating toward Noem at 19 percent compared to Sutton's 18 percent.
Noem's campaign manager Justin Brasell called the poll partisan in an emailed statement and said that it was "done by progressive Democrats to boost fundraising as he continues to sell a fake bill of goods." He then attacked Sutton's stance as a moderate.
ALG Research describes themselves as the "premier democratic polling firm in the United States."
