Fenno's Law is a political theory proposed by American political scientist Richard Fenno. It suggests that members of the U.S. Congress are more likely to prioritize the interests of their local constituents over national issues. This behavior stems from their need to be re-elected, leading them to focus on local concerns and projects that directly benefit their districts. According to Fenno, legislators engage in a process called "home style," where they cultivate relationships with their constituents. By doing so, they build trust and support, which is crucial for their political survival. This focus on localism can sometimes overshadow broader national interests.
