Thomas Grasaffi's objective, in his fascinating recent work, Coca Yes, Cocaine No, is twofold. He first aims to describe the shift of an agricultural and criminalized union of cocaleros (coca growers) into the ruling party responsible for governing Bolivia, the Movement Toward Socialism (Movimiento al Socialismo or MAS in Spanish); he then offers some key elements to understanding President EvoMorales's inability to adequately represent his base,which is composed of cocaleros unionmembers and leaders. Indeed, due to his international obligations (mainly toward the US) to stem coca cultivations and cocaine trafficking, Morales fell short of fulfilling cocaleros' expectations and hopes.
