Any analysis of López Obrador’s book “Grandeza” (Greatness) must start from its essentially political and ideological nature, rather than as an academic historical review. It is a text written based on assumptions about the past to explain and defend his vision of the present. López Obrador’s book is a gem for studying how a man imbued with Judeo-Christian values seeks to twist the human experience to fit his very particular vision of the universe and the humanity that inhabits it.
