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.
Luis Donaldo Colosio
Since Mexico's constitution permits presidents to remain in power for only one term, and as an extralegal rule presidents (until Salinas) handpicked their own successors (the party's first primary election in history took place in 1999), Colosio apparently continued to enjoy the president's favour, expressed in his famous declaration "No se hagan bolas: el candidato es Colosio" ("Don't get confused: Colosio is the candidate" would be an appropriate translation, literally it means "Don't entangle yourselves: Colosio is the candidate").
