RAPID CITY, S.D. (KBHB) – State Rep. Scyller (SKY’-ler) Borglum says she’s challenging U.S. Sen. Mike Rounds in a Republican primary.

Borglum, who was elected to her first term in the Legislature in November, portrayed herself as a “common sense conservative” as she kicked off her campaign Monday on her home turf in Rapid City.

Borglum says she would be a strong ally for President Donald Trump.

Rob Skjonsberg, a spokesman for Rounds, said in a statement that Rounds has stood with Trump more than 90% of the time.

Rounds, a former two-term governor, was elected to the Senate in 2014. He announced earlier this month that his wife Jean was beginning treatment for cancer.

Borglum says Rounds has lost touch with South Dakotans.

Borglum says she likes her chances because she feels residents in South Dakota are fed up with the status quo.

Borglum, who isn’t related to the Mount Rushmore sculptor, is traveling across South Dakota Monday as part of her announcement. She’ll be in Chamberlain at the Dignity Statue this afternoon and in Sioux Falls this evening.
