Tens of thousands of President Hugo Chavez's supporters filled the streets Friday vowing to win a vote on constitutional changes that would let the firebrand leftist seek re-election for years to come. Opponents called for close monitoring of results in what they expect could be a tight contest.
Chavez asked supporters to approve the reforms he said could keep him in power until 2050 - when he would be 95 years old - and said that a victory in Sunday's referendum would be a defeat for his enemies in Washington.
