We reviewed the candidate’s statements regarding the ten policy actions listed above. If we found at least one clear statement in support of the policy and no subsequent retraction or contradiction, the candidate received a “check” for that category. We considered all publicly available statements including plans and other statements on the candidates’ websites, statements made during debates and statements reported in the media, as well as social media accounts and responses to the Center for Biological Diversity Action Fund questionnaire. If we could not find a statement in support of the policy, or if the candidate has spoken affirmatively against the policy, the candidate received an “X” for that category.
