Our verdict

LiberalMind endorses Brock Greenfield

Election Day is November 3. Brock Greenfield, once the youngest person ever elected to the South Dakota Senate, seeks re-election as Commissioner of School and Public Lands — the office that manages the state's school lands and the investment returns they send to education. Raeann Mettler, a former Black Hills State professor with a PhD in natural sciences, is the Democratic challenger. No polling or race-specific finance figures were located. LiberalMind endorses Brock Greenfield. Read the research, and see why.

How South Dakota got here

Nominees were chosen at the parties' June state conventions, not in a primary (South Dakota Secretary of State's official 2026 General Election Candidate List; SD News Watch). The printed ballot, confirmed by the Secretary of State's list and the official Hanson County sample ballot: Brock Greenfield (R), the incumbent, filed 06/29/2026 and renominated at the GOP convention (GoWatertown); Raeann Mettler (D), filed 06/11/2026.

No race-specific finance figures or polling were located — no public competitiveness evidence was located. South Dakota Democrats have not won a statewide election since 2008 (Northern Plains News analysis).

Brock Greenfield (Republican) — the incumbent, with a start-date note printed honestly

Background and service: Commissioner of School and Public Lands — with a minor conflict in the sources on when his tenure began, printed as a conflict: SD News Watch says he "has been the commissioner of School and Public Lands since 2022," while the Argus Leader says he became commissioner in 2023 after 22 years in the Legislature. The research file frames the reconciliation as appointed in 2022, in office since January 2023 — appointed by Gov. Noem in 2022 and taking office at the start of the term — and we print it at exactly that framing, noting the two source dates rather than silently resolving them.

He was once the youngest person ever elected to the South Dakota Senate (Argus Leader 2026 ballot guide). His stated campaign priorities are maximizing investment returns to education and responsible land-lease management (Argus Leader, same guide).

Pros: An incumbent running on the office's core mission — returns to education and lease management — after a full term in the job and 22 years in the Legislature before it. His party renominated him without a documented contest.

Cons: The research located no detailed performance record for his term — no returns figures, no lease controversies, no audits — by which to grade the incumbency beyond its existence. That is a gap in the file, printed as a gap.

The flaw, plainly: No flaw proven in service was located in this research.

Raeann Mettler (Democratic) — the scientist challenger

Background and service: Of Spearfish; former Black Hills State University professor with a PhD in natural sciences; currently a research specialist in Indigenous public health for Missouri Breaks Industries Research (SD News Watch; Argus Leader ballot guide).

Her expertise — natural sciences, land-adjacent research — is relevant in kind to a lands office. No elected office, and no Manchin-test break with her party on our values, was located in this research.

Pros: Subject-matter credentials genuinely adjacent to the office: a natural-sciences doctorate and a university teaching record in the Black Hills.

Cons: No elected or land-management administrative record located; no located break with her party under the Manchin test; no located program for the office beyond the candidacy in this research.

The flaw, plainly: No conduct flaw was located. The priced item is the standard one: relevant expertise without an in-service record or a Manchin-test break does not displace a proven incumbent with no located flaw.

OUR CALL

LiberalMind endorses Brock Greenfield.

Greenfield is the proven incumbent — a term in this office on top of 22 years in the Legislature — running on the office's stated mission of returns to education and responsible leasing, with no flaw proven in service located against him. Mettler's scientific credentials are real and relevant in kind, and they are not a record of managing public lands or a proven break with her party. The start-date conflict in Greenfield's tenure (2022 vs. 2023) is printed above as the research frames it, not smoothed away. Endorse the incumbent.
