Returning to Peru he joined the Revolutionary Workers Party (POR) in Lima and participated in the famous protest to the then Vice-President of the United States, Richard Nixon, in 1958 . Following those demonstrations, Blanco caught the attention of the police, and decided to move to his home region to the Convencion Valley. Here he took residence in 1958 as a subtenant farmer, immersing himself in local politics. Beginning in 1958, with the help of students from the Cuzco University, Blanco’s Quechua federation mobilized the allegados against the hacendados and arrendires.
