Political researchers are frustrated that Facebook will not release aggregate data about political advertising on its platform, Reuters reports. They currently don't have any way to track political ad spend trends (frequency of ads, how they were viewed, creative that resonated with people, etc.).
Why it matters: As the law currently stands, candidates do not need to formally and publicly disclose political ad spend data on Facebook or any other digital property, like they have to with TV spending. Facebook, as they noted in an interview with Reuters, contractually guarantees its advertisers' discretion and will likely continue to honor that without a law in place to force them to act otherwise.
