areas of the United States (New York Daily News, 21 September 2006). The program was expanded in September 2006 to include four of New York City's five boroughs, earmarking 25 million gallons of fuel for low-income New York residents this year at 40% off the wholesale market price. That quantity provides sufficient fuel to heat 70,000 apartments, covering 200,000 New Yorkers, for the entire winter (New York Daily News, 21 September 2006). It has also been reported that Chavez is sending heating oil to poor, remote villages in Alaska. Some have questioned the motives of this generosity.

Constitutional referendum On 15 August 2007, Chavez called for an end to presidential term limits. He also proposed limiting central bank autonomy, strengthening state expropriation powers and providing for public control over international reserves as part of an overhaul of Venezuela's constitution.
