[1] In the 2009 mid-terms, Ríos Piter was elected to the Chamber of Deputies for the 61st Congress; his district, Guerrero's 3rd, was the only win for the PRD in the state that year.

[7] By early February 2018, he had reached the signature requirement—one percent of the electoral rolls in at least 17 of Mexico's 32 states—to appear on the 2018 presidential ballot as an independent, becoming the second candidate to do so behind Jaime Rodríguez Calderón.

[9] Ríos Piter also made calls to clear the political field, including Rodríguez Calderón and Margarita Zavala, and join forces to create a unified independent presidential campaign.
