In one of the elections that the San Juan PPD didn't completely collapse in, Soberanista Manuel Calderón Cerame was able to hold incumbent representative Víctor Parés Otero to a 1.46% Margin.
MCC was able to do this through holding Soberanista Melones in a similar fassion to the PPD Resident Commissioner candidate, Aníbal Acevedo Vilá.
Both ended up losing the district for diferent reasons, Acevedo Vilá because the vote againsed him was too much for him to overcome, and Calderón Cerame because the MVC and PIP combined held on too too many soberanistas for MCC to be able to win.
Manuel Calderón Cerame would later become the sole Municipal Legislator for the PPD once their incumbent resigned in the 2021-2024 Term, and is talked about as a potential future mayoral candidate, even if not favored to win.
