CLIZA, BOLIVIA - DECEMBER 16: A rural family picks potatoes to be bagged and shipped on December 16, 2005 in Cliza, Bolivia. Rural Indian workers, a long exploited and crucial sector of Bolivian society, have been a commanding force in the upcoming presidential elections in Bolivia, with most steadfastly behind Evo Morales. Morales, a one time coca farmer and union leader, is leading in the polls for the presidential election on December 18. Calling for the legalization of coca production and the nationalization of Bolivia?s natural resources, Washington is paying close attention to the race as fears grow of another Hugo Chavez in Latin America.
