Third party advertising refers to advertisements or other materials that support, promote or oppose a candidate, or support, promote or oppose a “yes” or “no” answer to a question on the ballot. Third party in this context is a person or entity who is not a candidate.
Third party advertising is separate from any candidate’s campaign, and must be done independently from a candidate. Any advertisements or materials that are made and distributed by a candidate, or under a candidate’s direction, are part of the candidate’s campaign.
