If Bernie Sanders publicly endorses Cori Bush in the 2026 MO-1 House election before Nov 3, 2026, then the market resolves to Yes. An endorsement requires a clear, affirmative statement of support for the nominee's election. The statement must be public (not private communications) and specifically reference the race or be clearly in context of the race. The endorsement must come directly from the person or through their official channels. Positive comments without explicit support, policy endorsements without nominee endorsement, or conditional endorsements do not qualify. Social media endorsements count only from verified accounts, and likes or retweets alone do not constitute endorsement. Quote tweets with additional supportive commentary do count. Sarcastic statements or those immediately clarified as jokes do not qualify. This market will close and expire early if the endorsement occurs.
