A COMPARATIVE ANALYSIS OF STATE GOVERNANCE MODELS: EVIDENCE FROM THE UNITED STATES

Abstract

This study examines the structure and functioning of state governance models through a comparative lens, with particular emphasis on the United States as a representative case of a presidential system. The article explores the institutional foundations of presidential governance, focusing on the separation of powers, the dual role of the president as both head of state and head of government, and the constitutional mechanisms that regulate executive authority. Special attention is given to the system of checks and balances, which ensures a dynamic equilibrium between the executive and legislative branches, thereby preventing the concentration of political power.
