Race at a glance
South Dakota State House District 12 will have a contested race in the Nov. 3, 2026, general election. The candidate field consists of Amber Arlint and Greg Jamison. Both are Republicans, and both currently hold office as incumbents.
That makes the contest one between candidates who share the same party label and already serve in elected office. The central choice for District 12 voters is which of the listed candidacies they want to support for State House representation. The general election is the deciding stage of the 2026 campaign.
The shared party label is an important feature of this race. It means voters will not be choosing between Republican and Democratic nominees in the listed candidate field. Instead, they will be considering two Republican incumbents in a race designated as contested.
Amber Arlint
Amber Arlint is running as a Republican incumbent for South Dakota State House District 12. Her incumbent designation means she already holds elected office while seeking another term in the chamber.
Arlint’s place in the race gives voters one candidacy with both a Republican affiliation and current officeholding experience. She will appear in the same District 12 contest as Jamison, who has the same party affiliation and incumbent status. Election Day is Nov. 3, 2026.
Greg Jamison
Greg Jamison is running as a Republican incumbent for South Dakota State House District 12. Like Arlint, his incumbent designation means he already holds elected office while seeking another term in the chamber.
Jamison’s place in the race gives voters a second candidacy with a Republican affiliation and current officeholding experience. He will appear in the same District 12 contest as Arlint, who also carries the Republican label and incumbent status. Election Day is Nov. 3, 2026.
What is contested
The contest concerns District 12’s representation in the South Dakota State House in the 2026 general election. The listed field includes two candidates rather than a single candidacy, and the race is designated as contested. Both candidates enter the election as sitting officeholders from the same party.
For first-time voters, the key details are straightforward: this is a State House race tied to District 12, not a statewide contest. The election is the 2026 general election, and voting is scheduled for Nov. 3. The candidates are Arlint and Jamison, and each is identified as a Republican incumbent.
As the election approaches, voters can follow the ballot process and any public campaign activity from each candidate. Because the candidates have matching party and incumbent labels, candidate statements and campaign priorities may help voters distinguish between them if those details emerge during the race. The outcome will be determined through the general election process rather than by party labels alone.
