Chavez's dying influence?

This article is about the defeat of Peruvian presidential candidate Ollanta Humala, who was openly supported by Venezuela's controversial president. Many attribute Humala's loss to the fact that Chavez approved of him in the first place. Furthermore, Chavez plans to endorse a Sandanista candidate in Nicaragua's upcoming presidential election. I wonder if this plan will backfire as well - if Nicaraguans are as fed up with him as many other Latin Americans. However, despite this animosity, it looks like major countries in Latin America, including Brazil and Chile, are planning on voting for Venezuela as a representative for the UN security council, despite pressures from the US to vote for Guatemala for the position. With the US and Chile currently cooperating under a free-trade agreement, what will happen when Chile's policy goes against Washington's wishes?
