Source-derived summary

The 1990 Wyoming gubernatorial election took place on November 6, 1990. Incumbent Democratic Governor Mike Sullivan ran for re-election. In the general election, he faced Republican nominee Mary Mead, a businesswoman and the daughter of former U.S. Senator and Governor Clifford Hansen. Owing to Sullivan's personal popularity, he won re-election over Mead in a landslide, marking the fifth straight Democratic victory in Wyoming's gubernatorial races, a streak that has yet to be broken by either party.

Duncan received a rating of 83%, Sidi received 79%, Scott received 66%, and Miller received 23%. Duncan withdrew from the election on March 2, 1990, stating that he was unable to convince people of the differences between him and Sullivan.

Tom Thorson, a Republican committeeman from Natrona County, announced Mary Mead's candidacy at the Natrona County Republican Convention on March 6, as Mead was unable to attend due to snow. Mead formally announced her campaign on March 9, after Duncan and Mike Lindsey both dropped out and announced their support of her.

Editorial summary

Begin with the source’s own compact description: “1990 Wyoming gubernatorial election” is open-knowledge reference entry. The dossier treats that line as a proposition to test through Wyoming, gubernatorial and election, not as a finished interpretation.

Editorial analysis

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.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 7, 2026. The linked authority identifier is Q30637454. The first chronological checks are 1990, 1966, 1970 and 1986.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
