He ran as the candidate for a three-party coalition dominated by the Democratic Revolutionary Party (PRD), the erstwhile political arm of the military dictatorship during the Torrijos and Norieiga years. A long-time member of the PRD, Pérez Balladares worked skillfully during the campaign to rehabilitate the PRD's image, emphasizing the party's populist Torrijos roots rather than its association with Noriega. He won the election with only 33% of the vote when the major non-PRD forces, unable to agree on a joint candidate, splintered into competing factions. His administration carried out economic reforms and often worked closely with the US on implementing the Canal treaties.
