The Social Christian Party (PSC) of Ecuador is a center-right party. The party's popularity is greatest on the coast, particularly Ecuador's economic center and most populous city, Guayaquil. The PSC is the most important party in coastal provinces such as Guayas, El Oro, Los Rios , Esmereldas , and Manabi , which constitute about half of the country's population. However, as a sign of how divided the country is regionally, the PSC has little power in the Andean region. Thus, while holding all major positions in Guayas and Guayaquil, the PSC has not held the presidential office since the highly effective presidency of Luis Febres-Cordero , who remains the power broker of the party.
