El siguiente trabajo tiene como objetivo principal someter a debate las formas del ejercicio del poder desarrolladas por el kirchnerismo en Argentina en el periodo 2003-2011. A tal efecto, se revisan las modalidades con que este logro hegemonizarse y se analizan los contenidos argumentales de las versiones que defienden el tipo liderazgo ejercido y aquellas que tienden a marcar sus limites debido al deficit en la llamada calidad institucional. En este sentido, para establecer esa discusion se utilizan como recursos teoricos de fondo la teoria adversarial de Ernesto Laclau y Chantal Mouffe y la perspectiva de la accountability o rendicion de cuentas interinstitucional de Guillermo ODonnell. Por otra parte, se realiza un detallado analisis de la gestion en materia de politicas publicas de los gobiernos de Nestor Kirchner y Cristina Fernandez a los efectos de determinar en que medida el desempeno del kirchnerismo en materia de politicas publicas ha significado en algunos puntos y en algunas areas un proceso de cambio importante respecto a la decada neoliberal."
