A public survey of likely general election voters across South Dakota showed Donald Trump and John Thune holding double-digit leads over their competitors.

The Remington Research Group conducted the survey Oct. 19-21, and 1,115 likely voters participated. There was a +/- 2.93 percent margin of error.

The survey asked which Presidential candidate the voter would chose if the election was held that day.

It showed 48 percent said Republican Donald Trump, 37 percent said Democratic Hillary Clinton, six percent said Libertarian Gary Johnson, two percent said Constitution Party candidate Darrell L. Castle, and eight percent were undecided.

It also asked which U.S. Senate candidate the voters would choose if the election was held that day.

It showed Republican John Thune ahead at 57 percent and Jay Williams at 36 percent. Seven percent were undecided.

“Donald Trump and Senator John Thune each hold double digit leads in their respected races,” said Titus Bond, Director of Remington Research Group, in a news release. “Unlike other states across the nation were polls show the tightening of races, South Dakota remains safe for the Republican candidates for President and Senate.

Furthermore, Donald Trump has maintained his lead despite Republican leaders within South Dakota, including Senator Thune, calling for him to withdraw the race.”
