base rate:
Zero Democratic wins in Oklahoma gubernatorial races since 2006 (5 consecutive cycles). Oklahoma PVI R+25-30. Last Democrat to win statewide was Brad Henry in 2006. Base rate for modern era: ~0-3%.
evidence updates:
Open seat (Stitt term-limited) pushes up by ~1-2%. Absence of identified Democratic candidates by April 3 filing deadline pushes down significantly. Nine Republicans filing including major figures (AG Drummond, former Speaker McCall) confirms GOP dominance. Three independents may fragment non-GOP vote further but unlikely to help Democrats. No polling shows Democratic competitiveness.
combination method:
The formal weighted average produces ~0.25, but this reflects analytical factor scores rather than outcome probability. The actual probability of a Democrat being inaugurated is determined primarily by structural conditions (sq1) and candidate quality (sq2), both pointing to very low probability. Final estimate reflects outcome probability ~4%.
final:
Oklahoma's deep Republican lean, absence of identified Democratic candidates past the filing deadline, strong Republican primary field, and historical pattern (zero Dem wins in 20 years) all point to very low probability. Open seat and possible midterm wave provide minimal upside. Final: 4%.
