- 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.
