Vice-President  Álvaro Marcelo García Linera, a principal author of the draft constitution, hailed Sunday's referendum results, saying, "this will be an egalitarian Bolivia, a Bolivia that leaves behind a dark, colonial, racist past." Linera, however, has acknowledged that the government has provoked deep divisions and faces vehement oppositions from many of the traditional elite, coming from many mixed-race people in the fertile eastern lowlands which rejected the draft charter.  "I am not saying there will be no more conflict, there will be tensions for a while, I say a decade ... but we will have built a state on three principles: the economy under state control, equality, and the territorial decentralization of power," he said. The new constitution was rejected in four opposition-controlled regions: the tropical lowlands of Pando, Santa Cruz, Tarija and Beni, which contain most of Bolivia's natural gas production and are responsible for most of its agricultural output.
