Ironically, the successful conclusion of negotiations with the United States and the signing of the Panama Canal treaties in August 1977 added to the growing political difficulties in Panama. Virtually all observers of Panamanian politics in the late 1970s agreed that the situation in the late 1970s could only be understood in terms of the central role traditionally played by nationalism in forming Panamanian political consensus. Before August 1977, opponents of Torrijos were reluctant to challenge his leadership because of his progress in gaining control over the Canal Zone. The signing of the treaties eliminated that restraint in short, after August 1977, Panamanian resentment could no longer be focused exclusively on the United States.

The widespread feeling among Panamanians that the 1977 treaties were unacceptable, despite their being approved by a two-thirds majority in the October 1977 plebiscite, contributed to growing opposition to the government. Critics pointed especially to the amendments imposed by the United States Senate after the October 1977 plebiscite, which they felt substantially altered the spirit of the treaties. Furthermore, political opponents of Torrijos argued that the government purposely limited the information available on the treaties and then asked the people to vote "yes" or "no," in a plebiscite that the opposition maintained was conducted fraudulently.

Another factor contributing to the erosion of the populist alliance built by Torrijos during the early 1970s was the graduated and controlled process of "democratization" undertaken by the Torrijos government after signing the new canal treaties. In October 1978, a decade after the government declared political parties illegal in the aftermath of the 1968 military coup d'état, the 1972 Constitution was reformed to implement a new electoral law and legalize political parties. In the spirit of opening the political system that accompanied the ratification of the Panama Canal treaties, exiled political leaders, including former President Arnulfo Arias, were allowed to return to the country, and a flurry of political activity was evident during the subsequent eighteen months. Foremost among the activities were efforts to obtain the 30,000 signatures legally required to register a party for the October 1980 elections.

The 1978 amendments to the 1972 Constitution markedly decreased the powers of the executive branch of government and increased those of the legislature, but the executive remained the dominant branch. From October 1972 until October 1978, Torrijos had acted as the chief executive under the titles of head of government and "Maximum Leader of the Panamanian Revolution." After the 1978 amendments took effect, Torrijos gave up his position as head of government but retained control of the National Guard and continued to play an important role in the government's decision-making process. Before stepping down, Torrijos had agreed to democratize Panama's political system, in order to gain United States support for the canal treaties. In October 1978, the Ned4 National Assembly elected a thirty-eight-year-old lawyer and former education minister, Aristides Royo, to the presidency and Ricardo de la Espriella to the vice presidency, each for a six-year term.

The PRD--a potpourri of middle-class elements, peasant and labor groups, and marginal segments of Panamanian society--was the first party to be officially recognized under the registration process that began in 1979. Wide speculation held that the PRD would nominate Torrijos as its candidate for the presidential race planned for 1984. Moreover, many assumed that with government backing, the PRD would have a substantial advantage in the electoral process.

In March 1979, a coalition of eight parties called the National Opposition Front (Frente Nacional de Oposición--FRENO) was formed to battle the PRD in the 1980 legislative elections, the first free elections to be held in a decade. FRENO was composed of parties on both the right and the left of center in the political spectrum, including the strongly nationalistic, anti-Yankee Authentic Panameñista Party (Partido Panameñista Auténtico--PPA), which was led by the aged but still popular former president, Arnulfo Arias the PLN the reform-oriented PDC and the Social Democratic Party (Partido Social Democrático--PSD), which was left of center and reform-oriented. Three right-of-center parties--the Republican Party (Partido Republicano--PR), the Third Nationalist Party, and PALA--had also joined the FRENO coalition. The Independent Democratic Movement, a small, moderately left-of-center party, completed the coalition. Such diverse ideologies in the opposition party suggested a marriage of convenience. FRENO opposed the Panama Canal treaties and called for their revision on terms more favorable to Panama.

All qualified parties competed in the 1980 legislative elections, but these elections posed no threat to Torrijos's power base because political parties vied for only nineteen of the fiftyseven seats in the legislature. The other two-thirds of the representatives were appointed, in essence by Torrijos's supporters. The PRD won twelve of the available nineteen seats the PLN won five seats, and the PDC, one. The remaining seat was won by an independent candidate running with the support of a communist party, the Panamanian People's Party (Partido Panameño del Pueblo-- PPP). The PPP had failed to acquire the signatures required for a place on the ballot. Despite the lopsided victory of the progovernment party and the weakness of the National Legislative Council (budgeting and appropriations were controlled by President Royo, who had been handpicked by Torrijos), this election represented a small step toward restoring democratic political processes. The election also demonstrated that Panama's political party system was too fragmented to form a viable united front against the government.
