Fenno is a term that can refer to various subjects, but it is often associated with Fenno's Paradox, a concept in political science. This paradox describes the phenomenon where voters express dissatisfaction with Congress as a whole while simultaneously supporting their individual representatives. This contradiction highlights the complexities of public opinion and electoral behavior. Additionally, Fenno can refer to Richard Fenno, a prominent American political scientist known for his work on congressional behavior and representation. His research has significantly contributed to the understanding of how legislators interact with their constituents and the implications for democratic governance.
