Race overview
South Dakota’s State House District 11 race is contested in the Nov. 3, 2026, general election. The candidate field consists of Brian Mulder and Keri Weems, both Republican incumbents.
Because the candidates share the same party affiliation and both currently hold office, party label and incumbency do not separate them. The contest instead gives District 11 voters a choice involving two sitting Republican lawmakers.
No policy positions are documented for either candidate. There also are no fundraising, spending or cash-on-hand figures on file for either campaign. That leaves no issue or financial comparison between Mulder and Weems at this stage of the race.
Brian Mulder
Brian Mulder is running as a Republican incumbent for State House District 11. Incumbent status means he currently holds the office he is seeking in the 2026 election.
Mulder has no candidate biography on file. His fundraising, campaign spending and cash-on-hand totals also are not on file. No policy positions are documented for his campaign, so there is not yet a stated platform to compare with Weems’ campaign.
Keri Weems
Keri Weems is running as a Republican incumbent for State House District 11. Like Mulder, she currently holds the office she is seeking in the 2026 election.
Weems has no candidate biography on file. Her fundraising, campaign spending and cash-on-hand totals also are not on file. No policy positions are documented for her campaign, leaving the same set of unanswered issue and financial questions as Mulder’s campaign.
What makes the race contested
The ballot contest is for State House representation in District 11, with Mulder and Weems listed as candidates for the 2026 general election. Both carry the Republican label, so the candidate field does not present a choice between political parties.
The central distinction currently visible to voters is the candidates’ identities. Both have the same listed party and the same incumbent status, while neither has documented policy positions, biographical details or campaign finance figures that create a broader public comparison.
That makes future campaign activity important to understanding the differences between them. Policy statements could show where Mulder and Weems agree or differ on state issues. Campaign finance filings could show how much each campaign has raised, spent and retained as cash on hand.
What comes next
The general election is scheduled for Nov. 3, 2026. Before then, voters can watch for changes to the candidate field, policy announcements from either campaign and the filing of campaign finance figures.
Those developments could add points of comparison, but the basic structure of the race is clear: two Republican incumbents, Brian Mulder and Keri Weems, are running in the contested State House District 11 election.
