“Prime contractors” pg 28

The Lincoln Project largely managed and performed its work through two prime contractors, as is standard operating procedure for political committees. These prime contractors were responsible for supervising and paying the teams of people that produced our prolific voter outreach efforts and advertisements. Many of those subcontractors received payment and worked underneath one of these contractors, not only because that is a normal commercial arrangement and standard industry practice, but because they had concerns for their privacy and safety in the face of an unpredictable and violent movement led by former President Trump. All prime contractors and subcontractors were paid in accordance with industry standards.

Note: This breakout only includes work conducted by Summit Strategic Communications and Tusk. Other costs associated with specific categories and The Lincoln Project's work are represented in the totals on page 29.

I can’t see anything how they operate beyond garbage in/out as we know - Ty u/purkiss80 good find to dig on
