This paper analyzes the first year of government of Mauricio Macri, leader of the Cambiemos coalition. His victory in 2015 over the candidate of the incumbent Front for Victory marked a turning point in the country's politics. We present the main political, social and economic events of the year and outline the fundamental positions of the new government in relation to these fields. We show the tensions of this center-right reorientation currently unfolding in Argentina, based on a vision of managerial modernization of politics and the state and controlled economic deregulation. We also explain how this project must deal with economic imbalances and social-structural conflicts, in addition to governing with a parliamentary minority and without control of most of the provincial governments.
