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.
Pascual Ortiz Rubio
Pascual Ortiz Rubio (; 10 March 1877 – 4 November 1963) was a Mexican politician and the President of Mexico from 1930 to 1932. He was one of three Mexican presidents to serve out the six-year term (1928-1934) of assassinated president-elect Álvaro Obregón, while former president Plutarco Elías Calles retained power in a period known as the Maximato. Calles was so blatantly in control of the government that Ortiz Rubio resigned the presidency in protest in 1932.
