In South Dakota, abortion opponents are reviving their campaign for an abortion ban two years after voters defeated it. The group VoteYesForLife.com says it has collected three times the needed signatures to put an anti-abortion measure back on the ballot this November. Two years ago, South Dakota voters rejected a measure that would have allowed abortions only to save a woman’s life. The latest measure is slightly less restrictive, also allowing abortions in the case of rape or incest.
