Though the results are still preliminary, it seems likely that the candidate for the left has won.
With an estimated real growth rate of 8.8% for 2010 (11th highest in the world for that year), the country remains fairly poor with a GDP per capita in Purchasing Power Parity of $9,200 (115th position). Unemployment rate currently stands at 7.9%, but inequality is high with a GINI coefficient of 49.6 (25th highest in the world). The poorest ten percent of households have 1.5% of total income/consumption while the top ten percent has 37.9%.... It is not hard to imagine why people supported the candidate with the redistributive agenda. For more background information and sources, go here.
