Nearly 20 years after South America's longest-serving president, Evo Morales, was elected on a promise of socialist revolution, the Andean country is running on empty.

Widespread shortages of dollars, fuel and basic foodstuffs have left some Bolivians worse off than before Morales took over.

Polls predict electoral catastrophe for the ruling Movement towards Socialism (MAS), which survived the fall of many leaders in Latin America's "Pink Tide" - a wave of left-wing governments across the region.
