YANKTON, S.D.(WNAX)- Many republican candidates for office this year are finding voters from their own party are the most critical.

South Dakota Senator John Thune says he is hearing it.

Thune says he expects most republicans will stick with him.

Thune says former President Trump does cast a shadow over the fall elections.

Thune faces democrat Brian Bengs and libertarian Tamara Lesnar in November.
