Senate at-large

The Popular Democratic Party decided to nominate four candidates instead of six candidates like they normally do, claiming that this would help them win more overall at-large seats. Although the Citizen's Victory Movement originally planned to have two at-large candidates, these being incumbent senator Rafael Bernabe Riefkohl and newcomer Alejandro Santiago Calderón, their candidacies were invalidated by the Supreme Court for not having collected the necessary endorsements required by law.
