“…One definition is offered by Kingdon (, 21): “[a]n actor who advocates and seeks to change policy by exploiting opportunities and employing entrepreneurial strategies.” Mintrom (, 36), writing from a public policy perspective, adds, “[t]hey are individuals who through their creativity, strategy, networking, and persuasive argumentation are able to bring new policy ideas into the open and promote policy change.” Another definition is provided by Mazarr (, 16) who, writing from a constructivist perspective, states that “[p]olicy entrepreneurs can be seen as the human embodiment of the social construction of policy… . Advocates determined, for one reason or another, to fight inertia, the bureaucracy, opposing interests, and anything else in their way to get the idea through the window [of opportunity] and into law or policy.” These three definitions complement each other and are useful for this research.…”
