On 21st February 2016 Bolivia held a referendum over whether the constitution should be ammended to allow the president and vice president to stand for a 3rd consecutive term in the 2019 elections (currently they can only serve for 2 terms). The No vote narrowly won. This propaganda was for the Yes campaign, thanking Evo Morales for bringing the Dakar Rally to Uyuni and also for plans to industrialise Bolivia's lithium reserves (the Salar de Uyuni is estimated to contain at least half the world's lithium).
