South Dakota's Senate District 27 race, claim by claim

Endorses Kathol

Update — October 25, 2026: Verification review adds two sourced facts the original article's template missed. (1) Peri Pourier is not a record-less independent: she is the sitting District 27 state representative, elected as a Democrat, who switched her affiliation to Republican in September 2025 and lost the June 2026 Republican convention vote for Public Utilities Commission before filing for Senate as an independent (South Dakota News Watch / Argus Leader). Her House record was not verified at this pass's depth, so the endorsement of the Republican nominee below stands on caucus math, stated openly. (2) Endorsee Anthony Kathol challenged the nominating petitions of Celestine Stadnick in this race (and of a House candidate in District 27); a circuit court ruled Stadnick had enough valid signatures, and Kathol's appeal to the state Supreme Court was pending at last report (South Dakota Searchlight). Ballot-access litigation by our endorsee against his opponent is a fact voters should have; it is printed, not priced. ## The race

Senate District 27 elects 1 seat in 2026. The incumbent of record is Red Dawn Foster (Democratic). The seat is open: the incumbent is not on the general-election ballot. On the confirmed general-election roster (Ballotpedia compilation; see Sources): Celestine Stadnick (Democratic), Anthony Kathol (Republican), Peri Pourier (Independent).

Celestine Stadnick (Democratic). On the compiled record, Celestine Stadnick is a confirmed general-election candidate for this seat. No detailed voting-record or biography file beyond the roster was verified at this sourcing depth, and we do not invent one.

Pros: Gives voters who disagree with the Republican program a choice on the ballot; steelmanned, that choice is the honest core of the candidacy. Cons: A party-line Democrat with no Manchin-test break located — no proven in-service break with their party toward our values. The organizing vote is HEAVY in the Senate: a Democratic majority controls confirmations and the judicial pipeline compounds for decades. The flaw, plainly: Enabler class, not extremist — a reliable party-line vote, which is the standing reason the exception for a Democrat is not earned here. No personal-program extremist classification is made: none was documented.

Anthony Kathol (Republican). On the compiled record, Anthony Kathol is a confirmed general-election candidate for this seat. No detailed voting-record or biography file beyond the roster was verified at this sourcing depth, and we do not invent one.

Pros: Runs under the party whose program — Constitution, free markets, faith, freedom — this publication supports; Republicans are in-tent, and intra-party questions are priced on records, not faction labels. Cons: No proven in-service flaw meeting this publication's standard was located in the compiled record. The flaw, plainly: None proven was located in the compiled record.

Peri Pourier (Independent). On the compiled record, Peri Pourier is a confirmed general-election candidate for this seat. No detailed voting-record or biography file beyond the roster was verified at this sourcing depth, and we do not invent one.

Pros: Offers voters an option outside both party programs. Cons: No record toward this publication's values was verified at this sourcing depth; an unproven candidacy is a watch posture, not a demerit — but it does not displace a Republican on this record. The flaw, plainly: None proven was located; equally, no affirmative case on our values was documented.

OUR CALL

We endorse Anthony Kathol. The endorsement is of a candidate without prior service in this seat — as unproven, and on watch. The reasoning is the doctrine applied to the sourced roster: no proven flaw was located against the endorsed candidate(s), no Democratic candidate on this ballot passed the Manchin test, and no extremist classification was documented for any candidate — so the call rests on party program and caucus math, stated openly.

Vote early. Research your candidates. Choose the best moderates, whatever their party — no extremism from either side. And encourage your friends and family to do the same.
