With national support, Democrat Dan Ahlers could upset Do Nothing Republican Mike Rounds. SD Republican Governor Noem is not popular and Senator John Thune has lost touch with South Dakotans. The uneasy mix is right for exploitation. Rounds is beatable but the National Dems have poor knowledge of their party.
