Despite an increase of advocacy by established nongovernmental sport organizations, little is known about how advocacy is enacted and with what effects. Building conceptually on frame alignment theory and empirically on interview data from 19 Swedish Regional Sport Federations, this article investigates how advocates politicize sport to gain “insider status” and analyses the by-products of such efforts. This research demonstrates that the architecture of advocacy claims perpetuates a separation between organizations that “sell” sport from those that “produce” it. Framing also impels centralized authority because advocates safeguard their credibility as political actors by taking up a “leadership-position” vis-à-vis clubs. Advocacy frame alignment has further by-products insofar as they narrow advocates’ room for maneuver and become institutionalized over time.
