El circo (song)
The lyrics describe two brothers, "Carlos" and "Raúl" (in reference to Carlos Salinas de Gortari, president of Mexico from 1988 and 1994, and his brother Raúl Salinas de Gortari), who form a "circus" (a drug cartel) and get rid of the other "circuses" in the country. After the brothers get wealthy, Raúl makes Carlos' money disappear (a reference to the Mexican peso crisis) and their circus ends. Raúl is jailed, while Carlos leaves the country, and the people are finally at peace, unless another circus arrives and the story repeats itself.
Politics of Mexico
The presidential elections held in 1988 marked a watershed in Mexican politics, as they were the first serious threat to the party in power by an opposition candidate: Cuauhtémoc Cárdenas, who was nominated by a broad coalition of leftist parties. He officially received 31.1 percent of the vote, against 50.4 percent for Carlos Salinas de Gortari, the PRI candidate, and 17 percent for Manuel Clouthier of the National Action Party (PAN). It was believed by some that Cardenas had won the election, but that the then government-controlled electoral commission had altered the results after the infamous "glitch in the system" ("se cayó el sistema", as it was reported). In the concurrent elections, the PRI came within 11 seats of losing the majority of Chamber of Deputies, and opposition parties captured 4 of the 64 Senate seats—the first time that the PRI had failed to hold every seat in the Senate. Capitalizing on the popularity of President Salinas, however, the PRI rebounded in the mid-term congressional elections of 1991, winning 320 seats.
