PIERRE — Doubts about a person’s citizenship status could be used to challenge their right to vote in South Dakota, if a proposal approved by a legislative committee Wednesday becomes law. A person initiating a challenge would have to be registered to vote in the same county as the person being challenged. ADVERTISEMENTThe Secretary of State’s Office, which oversees elections in South Dakota, requested the bill . Sen. Liz Larson, D-Sioux Falls, was the only Senate State Affairs Committee member to vote against the measure. She raised concerns about what evidence or proof is needed to challenge a person’s vote and whether the state should give everyday citizens that authority.
