Sandinista loss in 1990 are disputed. Defenders of the defeated government assert that Nicaraguans voted for the opposition due to the continuing U.S. economic embargo and potential Contra threat. Others have alleged that the United States threatened to continue to support the Contras and continue the civil war if the regime was not voted out of power. After their loss, the Sandinista leaders held most of the private property and businesses that had been confiscated and nationalized by the FSLN government. This process became known as the "piñata" and was tolerated by the new Chamorro government. Ortega also claimed to "rule from below" through groups he controls such as labor unions and student groups. Prominent Sandinistas also created nongovernmental organizations to promote their ideas and social goals. Ortega remained the head of the FSLN, but his brother Humberto resigned from the party and remained at the head of the Sandinista Army, becoming a close confidante and supporter of Chamorro.

Municipal elections in November 2000 saw a strong Sandinista vote, especially in urban areas, and former Tourism Minister Herty Lewites was elected mayor of Managua.

Daniel Ortega and Enrique Bolaños of the Constitutional Liberal Party (PLC) ran neck-and-neck in the polls for much of the campaign, but in the end the PLC won a clear victory. The results of these elections were that the FSLN won 42.6% of the vote for parliament (versus 52.6% for the PLC), giving them 41 out of the 92 seats in the National Assembly (versus 48 for the PLC).
