FILE - In this July 14, 2012 file photo, Venezuela's President Hugo Chavez speaks to supporters at a campaign rally in Barquisimeto, Venezuela. When he takes the stage at campaign rallies, Chavez stands alone. Under Venezuela's election system, presidential hopefuls don’t choose running mates. The lack of a No. 2 leaves voters with a big unknown ahead of next month's presidential election and raises question about who in fact would take over were Chavez to win and leave office prematurely.
