As reported in Slate Magazine: Can a Dead Woman Vote?

At the conclusion of her victory speech in Charleston, W.Va., on Tuesday night, Hillary Clinton told the story of a supporter named Florence Steen, who passed away last Sunday. The 88-year-old South Dakotan had just voted for Clinton by absentee ballot, ahead of the state's June 3 primary. It's a touching story, but will her vote still count?
No. As dictated by a 2001 state law, the South Dakota Department of Health is responsible for furnishing the county auditors with a list of registered voters who have died each month. This information is used to update the state's electronic voter-registration file, which was created by a different 2001 law. Absentee ballots are collected by county auditors and remain sealed until the election, so if an absentee voter dies prior to the election, then her ballot is never opened.
The 2001 South Dakota law originally required this monthly list of deceased voters to be transferred to the county auditors by the 10th of the following month—which in this case could have occurred after the June 3 election. However, updates to the legislation passed in the wake of 2002's Help America Vote Act now require more frequent electronic reporting.
