WASHINGTON (KSFY) - The balance of power in the United States House and Senate are up for grabs this Midterm Election, and people in South Dakota, Minnesota and Iowa will play a role in determining who holds the cards on Capitol Hill.
South Dakotans will choose their new U.S. Representative as Congresswoman Kristi Noem gives up her seat for a run for governor.
Republican Dusty Johnson and Democrat Tim Bjorkman are fighting for South Dakota's only seat.
Political expert Gary Nordlinger told KSFY's Washington Bureau if that seat turns blue, that signals a Democratic tsunami nationwide.
"This should be a Republican seat in a Republican state," he said.
Iowans in the fourth district will choose whether to keep their congressional seat in GOP hands with incumbent Congressman Steve King facing a challenger in Democrat J.D. Scholten.
A Scholten victory could play a role in giving Democrats control of the people's house.
Across the state line, Minnesotans will choose who will represent them in the United States Senate. Democratic Sen. Amy Klobuchar is facing a challenge from Jim Newberger.
Nordlinger said Klobuchar's popularity and role on the powerful Senate Judiciary Committee give Newberger an uphill battle.
Sen. Tina Smith on the other hand was appointed earlier this year after the exit of Al Franken. She is facing a challenge from Republican Karin Housley who has her sights set on adding to GOP control in Washington.
"If Tina Smith loses and there's a national trend here, it just means it's not as a great a year for the Democrats as they're hoping for," Nordlinger said.
Nordlinger said President Donald Trump's influence could have an impact in a purple state like Minnesota. He lost in that state by two points in 2016, but these midterms could show if he and his party have picked up more support in the Land of 10,000 Lakes.
