Interest Groups and Political Lobbying:

Abstract

This study investigates the role of interest groups and political lobbying in shaping U.S. domestic policy during Barack Obama’s presidency (2009–2016). Despite Obama’s campaign rhetoric against lobbyists and his administration’s efforts to curb their influence through executive orders and regulatory reforms, lobbying persisted as a powerful force in American politics. Using a qualitative case study approach, this research examines lobbying strategies and campaign finance patterns across key policy areas, including healthcare, financial regulation, climate change, education, and immigration. Special attention is given to the transformative impact of judicial decisions such as Citizens United v. FEC (2010), which redefined the legal framework of political spending. The study demonstrates how interest groups adapted to new regulatory landscapes, employing both direct and indirect strategies to maintain influence over legislation and policymaking. Findings reveal enduring tensions between public policy objectives and private interests, underscoring the structural limits of executive action in restraining entrenched lobbying practices. Ultimately, the current work argues that lobbying remains a constitutionally protected but deeply contested feature of American democracy. Effective regulation, therefore, requires continuous institutional reform to balance democratic accountability with the competing pressures of organized interests.
