"In Davison County, election officials improperly counted over-votes On ballots where two Senate candidates had been marked, the election officials decided to block out the mark given to the candidate with the ‘lighter’ mark. These marks were covered with small, round, white stickers. Election officials were videotaped blocking votes from Congressman Thune. Concerns were also raised in Davison County because operatives working for Senator Tim Johnson’s office were initially granted access to the Democratic auditor’s office and its computers without allowing similar access to other parties."
