2004 United States Senate election in Oklahoma
Open-knowledge reference entry

The 2004 United States Senate election in Oklahoma took place on November 2, 2004. The election was concurrent with elections to the United States House of Representatives and the presidential election. Incumbent Senator Don Nickles decided to retire instead of seeking a fifth term. Fellow Republican Tom Coburn won the open seat. This was the last open-seat Oklahoma U.S. Senate race until 2026, and the last election for this seat in which the Republican nominee did not win every county.

Campaign
Humphreys, the former mayor of Oklahoma City, ran for the United States Senate with institutional conservative support, namely from Senators Don Nickles and Jim Inhofe, as well as former Congressman J. C. Watts. However, Coburn received support from the Club for Growth and conservative activists within Oklahoma. Humphreys noted, "[Coburn is] kind of a cult hero in the conservative portion of our party, not just in Oklahoma. You can't get right of the guy." Much of Coburn's celebrity within the Republican Party came from his tenure in Congress, where he battled House Speaker Newt Gingrich, who he argued was moving the party to the center of the political spectrum due to their excessive federal spending. Coburn's maverick nature culminated itself in 2000 when he backed conservative activist Alan Keyes for President rather than George W. Bush or John McCain.
Begin with the source’s own compact description: “2004 United States Senate election in Oklahoma” is open-knowledge reference entry. The dossier treats that line as a proposition to test through United, States and Senate, not as a finished interpretation.
Why this record matters
The phrase “open-knowledge reference entry” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 27, 2026. The linked authority identifier is Q7891899. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2004, 2026 and 2000.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
