Chavez and his Cuban handlers are relentlessly and systematically eliminating every aspect of democracy. There will never be a referendum.
The only way Chavez will ever leave office is when he either (1) Assumes room temperature, or (2) Jets off to enjoy his Swiss bank account fortune one step ahead of the revolution.
BOYCOTT CITGO!!!! (Chavez' personal oil company)
Anyone who's watched Chavez, knew from the get-go there would never be a referendum. Carter knew too. His visit helped pour cold water on the opposition's momentum.
