Polls are suggesing that Evo Morales, the Bolivian president, is likely to clinch a first-round win in Sunday's national election.
The populist leader has already nationalised the country's natural gas reserves, ushered in a new constitution and re-distributed land to the nations' indigenous majority.
While his first term in office has made him immensely popular among Bolivia's poor, it has also antagonised the country's traditional powerbrokers.
Now Morales is trying to reach out to the country's middle class.
