History
Pedro Múñoz, deputy, and lawyer Roberto Suñol were initially confirmed. Former pre-candidate Rafael Ortiz Fábrega is in a diplomatic posts abroad. In December 2020, several representatives of the party faction known as "Unity People" sent a letter to former president Rafael Ángel Calderón Fournier, with the purpose of talking about establishing a coalition with his current party, the Social Christian Republican Party and other ideologically similar parties for the 2022 election. Former President Miguel Ángel Rodríguez Echeverría, who is still a PUSC member supported the idea of a PUSC-led coalition, yet said proposal was denied by the party's Executive President, Randall Quirós Bustamante, allegedly due to lack of time.

On February 7, 2021, the party's National Assembly voted 56-32 against Former President Rodriguez Echeverría's motion for an electoral coalition led by the Social Christian Unity Party and with the participation of "Social Christian, Conservative, Liberal, and Evangelical political groups."
