The Popular Democratic Party (, PPD) is a political party in Puerto Rico that advocates for the current status of the archipelago and island as an estado libre asociado (commonwealth), an unincorporated territory of the United States with constitutional self-governance. The party was founded in 1938 by dissidents from the Puerto Rican Liberal Party and the Unionist Party.

As one of the long-standing parties on the island, the PPD has played a significant role in the history of Puerto Rico. In the early 1950s, for example, the party held a majority in the delegation convened to draft the Constitution of Puerto Rico. Once the constitution was ratified, the document was proclaimed by the party's leader and co-founder, Luis Muñoz Marín—who, in doing so, became the first Puerto Rican governor elected by the people of Puerto Rico. Since 1952, the party has ruled all branches of the Puerto Rican government for a total of 36 years, while establishing many of the institutions that permeate Puerto Rican society today.

Today, the party is one of the two major parties in Puerto Rico with significant political strength. In the executive branch, the party's most recent governor was Alejandro García Padilla who governed the island from 2013 to 2017; while in the legislative branch, the party is the largest in both the House and the Senate, though it is short of an overall majority in both. On the Supreme Court, the party is in the minority, though the Chief Justice of the Supreme Court is from the PPD; a circumstance that allows the party to designate political appointees in the judicial branch since the chief justice is also constitutionally the chief judicial administrator. Finally, in the municipal landscape, the party holds more than half of the seats of mayors.

Ideologically, the PPD differs from the other parties active in the island. Historically, for example, the party's opponent has been the New Progressive Party (PNP in Spanish). Both parties have ruled the island unopposed for years after the Puerto Rican constitution was ratified in 1952.

Members of the party are referred to in different terms depending on their faction. In general, those affiliated to the party are commonly called populares (English: "populars") and mostly affiliate with the Democratic Party of the United States. Internally, members aligned with the delegation that drafted the constitution compose the largest faction and are referred to as 'conservatives'. A smaller 'liberal' faction is referred to as the soberanistas, and advocates for Puerto Rico to enter a compact of free association with the United States rather than remain an unincorporated territory under the United States.

History

Foundation Dissidents expelled from the Liberal Party of Puerto Rico (then led by Antonio R. Barceló) founded the PPD in 1938. Many of them were part of the old socialist movement of Puerto Rico. The dissident faction, initially calling themselves the Partido Liberal, Neto, Auténtico y Completo ("Clear, Net, Authentic, and Complete Liberal Party") (PPD), was led by Luis Muñoz Marín. In 1937, the debate had concerned the differences between the moderate demands of autonomy leading to gradual independence by the Liberal Party faction led by Barcelo, and the desire for more radical demands of immediate independence and social reform by Muñoz and his followers.

1940s In 1940, the highest elective political office in Puerto Rico was as president of its Senate. At the time, the governor was appointed by the president of the United States; no native-born Puerto Ricans were appointed to the post until 1946, when Jesús T. Piñeroone of the original founders of the PPDwas appointed by U.S. President Harry S. Truman.

In the 1940 election, the Popular Democratic Party of Puerto Rico (PPD) finished in a dead heat with the Liberal Party. Luis Muñoz Marín of the PPD brokered an alliance with minor Puerto Rican factions so as to secure his position as Senate president; such coalition-building was fundamental to the multi-party society. The elections in 1944 and 1948 resulted in greater victory margins for the PPD; nearly all the legislative posts and mayoral races in Puerto Rico were won by PPD candidates.

On May 21, 1948, a member of the PPD introduced a bill before the Puerto Rican Senate which would restrain the rights of the independence and nationalist movements on the archipelago. The Senate, which at the time was controlled by the PPD and presided by Muñoz Marín, approved the bill. This bill, which resembled the anti-communist Smith Act passed in the United States in 1940, became known as the Ley de la Mordaza (Gag Law, technically "Law 53 of 1948") when the U.S.-appointed governor of Puerto Rico, Piñero, signed it into law on June 10, 1948.

Under this new law it became a crime to print, publish, sell, or exhibit any material intended to paralyze or destroy the insular government; or to organize any society, group or assembly of people with a similar destructive intent. It made it illegal to sing a patriotic song, and reinforced the 1898 law that had made it illegal to display the Flag of Puerto Rico, with anyone found guilty of disobeying the law in any way being subject to a sentence of up to ten years imprisonment, a fine of up to US$10,000 (), or both, for each offence. According to Dr. Leopoldo Figueroa, a non-PPD member of the Puerto Rico House of Representatives, the law was repressive and violated the First Amendment of the US Constitution which guarantees Freedom of Speech. He pointed out that the law was a violation of the civil rights of the people of Puerto Rico. Numerous Nationalists were arrested under the law, and Figeroa defended 15 of them. He also defended a man in a case taken to the US Supreme Court, to challenge the "Gag Law" on the basis of the government's not having had sufficient evidence to arrest the suspect. The Supreme Court upheld the constitutionality of the law.

Once Jesús T. Piñero stepped down as the last U.S.-appointed governor, the governor's office became an elected position. In 1949, under the leadership of Muñoz Marín, the PPD won the first gubernatorial elections in Puerto Rico, and Muñoz became the first elected governor of the island.

He served for what is the longest rule by any of the nearly 200 governors (starting with Juan Ponce de León in 1508) in Puerto Rican history, being re-elected three times, and serving a total of four 4-year terms, or 16 years.

1950s During the 1950s, Luis Muñoz Marín was twice re-elected (1952, 1956) as Puerto Rico's governor. In 1952 he assumed the responsibility of pushing forward the drafting of a constitution to create the Commonwealth of Puerto Rico. The constitution was passed by the legislature and overwhelmingly approved by the people with an 82% vote. On July 25, 1952, the new constitution went into effect. Munoz pushed his political-financial platform, called Operation Bootstrap (Operación Manos a la Obra), in which he stimulated Puerto Rico's economy to develop industry. Teodoro Moscoso was in charge of the project.

1960s Muñoz Marín was re-elected in 1960, his fourth consecutive term. In 1964, Muñoz Marín chose not to run for a fifth term. Roberto Sánchez Vilella, representing the PPD, became the second governor to be democratically elected in Puerto Rico. The party remained in control of the governor's office until 1968.

By the time of the 1968 election, personal and irreconcilable differences had developed between Sánchez Vilella and PPD party president Muñoz Marín. Muñoz Marín opposed Sánchez Vilella's attempt to run for reelection. At a PPD party assembly, Munoz nominated Luis Negrón López as his candidate for governor, ruining any chance that Sánchez Vilella would be considered in the party's primary process.

Sánchez Vilella left to create a new party called the People's Party (Partido del Pueblo, PP). The PP's motto was "Que el pueblo decida", (Let the people decide). The motto was obviously directed at Muñoz Marín, who denied Sánchez Vilella a chance to compete in a party primary.

With Sánchez Vilella and Negrón López competing as candidates for differentbut nearly identicalparties, the electorate split their votes. Luis A. Ferré of the New Progressive Party (Partido Nuevo Progresista, PNP), which advocates for statehood, won the gubernatorial election with a plurality of votes among the three major parties. This was the first defeat of the PPD in a general election since its founding.

1970s By 1972, the PPD had a young and fresh leader in former senate president Rafael Hernández Colón. After the 1968 electoral defeat, Muñoz Marín left the island and went into "exile" in Italy to stay away from local politics and let the PPD find its new direction without him.

Muñoz Marín did not return to Puerto Rico until the PPD had selected Hernández Colón as its new leader and candidate for governor. Muñoz Marín introduced him before 300,000 people in Hato Rey at a party meeting. In the 1972 general election, Hernández Colón defeated Ferré by a wide margin, and his party won in all but four municipalities. In 1976, Carlos Romero Barceló, mayor of San Juan and the PNP candidate, defeated Hernández Colón.

1980s In 1980, Rafael Hernández Colón ran again as the PPD gubernatorial candidate. Controversy arose when PPD followers alleged that there were irregularities during the vote count. The power went out during the night while results were being counted. PPD supporters said that, before the power went out, the vote count was favoring Hernández Colón, but when the power was restored, results started favoring Romero Barceló. The Populares alleged fraud and Hernandez Colón said, "Populares, a defender esos votos a las trincheras de la lucha." (Populares, let's fight for those votes in the trenches). After the recount, Romero Barceló of the PNP won by 3,000 votes. The PPD won almost every other part of the election.

In 1984, Hernández Colón was elected again as governor, defeating his long-time political rival Romero Barceló of the PNP. His second term was marked by his successful fight to keep federal Law 936 (U.S.C. TITLE 26, Subtitle A, CHAPTER 1, Subchapter N, PART III, Subpart D, § 936, "Puerto Rico and Possession Tax Credit") in force. The PDP had helped establish the law, which gave tax breaks to American companies operating in Puerto Rico in order to encourage new businesses.

In 1988, Hernández Colón was re-elected by a comfortable margin, defeating Corrada del Río of the PNP. The two candidates conducted a formal debate on issues. That same year Héctor Luis Acevedo, the PPD mayoral candidate for San Juan, won the San Juan mayoral race by only 49 votes.

In 1988, Santos Ortiz, a.k.a. "El Negro", mayor of Cabo Rojo, left the PPD. He ran for mayor in the next election as an independent, and was the first person not affiliated with Munoz Marin and any of the three major parties in Puerto Rico to win an elected position.

1990s

In 1992, after Hernández Colón decided not to run for governor again, the PPD elected Victoria Muñoz Mendoza, daughter of Luis Muñoz Marín, as its candidate. The first woman in Puerto Rican history to run for governor, she lost the election to Pedro Rosselló.

In 1996, Héctor Luis Acevedo ran for governor from the PPD, but lost to Roselló. That year, the PPD won San Juan mayoralty with its candidate, Sila María Calderón.

Plebiscites on political status The opposition party, PNP, led two campaigns for Puerto Rican statehood in 1993 and 1998. Locally enacted plebiscites were held to consult the Puerto Rican people on the issue of future political status of the island in relation to the United States. In 1993 the PPD campaigned in favor of the status quo Commonwealth, while the PNP opposition campaigned for full statehood. Voters supported continuation of the Commonwealth option, which received 48% of the votes.
