Venezuelans line up before casting their vote during the presidential elections in Caracas October 7, 2012. Venezuelans vote on Sunday with President Hugo Chavez facing the biggest electoral challenge yet to his socialist rule from a young rival tapping into discontent over crime and cronyism. Henrique Capriles, a centrist state governor, edged toward the still popular Chavez in final polls thanks to a vigorous campaign that united the opposition and made him its best chance of ending Chavez’s 14-year rule.
