Candidate Background and Public Filings

The 3 public source claims in OppIntell's database are all validated, meaning they come from official or credible public sources.

What Opposition Researchers Would Examine

- **Public Statements**: Speeches, interviews, social media posts, and op-eds. Any controversial or inconsistent statements could be used in attack ads or debate questions.

- **Community Involvement**: Nonprofit work, endorsements from local leaders, and participation in community events. This could be used to demonstrate either deep roots or lack of engagement.

Because Campbell's profile is still being built, much of this information may not yet be publicly available. Campaigns should revisit the OppIntell profile regularly as new sources are added.
