Once I start looking at the voter registration tables, I just keep going:
- Registered Republicans don’t make up a majority of South Dakota voters yet, but they are creeping close to 50%. As of August 17, 2022, 291,342 Republicans made up 49.52% of all registered voters in South Dakota. (Republicans haven’t been below 45% of South Dakota’s electorate in the last 16 years.)
- Democrats dropped below 26% of the electorate as of June 1. As of August 17, they have slid to 150,712 registrants, 25.62% of the electorate. Democrats were last above 30% of the electorate in March 2018; their recent historical high was 38.53% for the 2008 general election.
- Independents climbed above 24% of the electorate for the first time in February 2021, but their percentage has plateaud since. After peaking at 143,328 registrants and 24.35% of the electorate in September 2021, independents have declined to 142,170 registrants and 24.17% of the electorate. When the Secretary of State was lumping third-parties in with the indy count, those non-GOP/non-Dem voters made up just 14.71% of the electorate.
- The gap between Democrats and independents dropped below 10,000 some time in May; as of August 17, South Dakota had just 8,542 more Democrats than registered independents in South Dakota, a gap of 1.45 percentage points out of the total electorate.
- Independents outnumber Democrats in 16 counties, including 8 of the 10 counties with the largest voter rolls: Pennington, Meade, Lincoln, Union, Lawrence, Brookings, Minnehaha, and Yankton.
- Democrats outnumber Republicans in 9 counties: Oglala Lakota, Todd, Dewey, Roberts, Buffalo, Ziebach, Corson, Clay, and Bennett. Clay ranks 14th for total voter registration; Oglala Lakota ranks 15th; Roberts, 19th. The other six Democratic counties each have fewer than 5,000 total voters. Clay is the only Democratic-dominated county not on or adjacent to an Indian reservation.
- The percentage of Republican voters is greater than the percentage of Democratic voters by over 50 points in 15 counties. Harding, Campbell, and Haakon counties have GOP advantages over Dems of greater than 70 percentage points. The largest county with a 50+ point GOP advantage is Butte, with 4,223 Republicans and 840 Democrats out of 6,501 voters total, a 52-percentage-point gap. Butte is the 18th-largest county by total voter registration; none of the other 50+ point GOP advantage counties have more than 5,000 voters total.
