The purge that occurs every two years when county auditors clean up their voting rolls appears to have taken out significant shares of registered voters in South Dakota during the past month.
Republicans, Democrats and others/independents are all down in the latest monthly registration totals released Tuesday by the secretary of state.
Republicans dropped from a peak of 243,881 on Sept. 1 to a current low of 237,636, including a drop of 1,116 since Dec. 1.
Democrats took worse losses than Republicans, however. They dropped from 175,172 on Sept. 1 to 167,272 as of Tuesday, including a tumble of 2,053 since Dec. 1.
The all-others category including independents suffered losses too. From an all-time high of 111,577 on Sept. 1, they were down to 108,766 on Tuesday, including a decline of 737 since Dec. 1.
Compared to two years ago, however, there has been significant change. Republicans number about 2,900 more currently, while Democrats are down about 9,500. Others/independents are up nearly 14,000.
