Prolonging a bitter campaign that has pitted rich against poor, Venezuela’s highest court suspended this weekend’s presidential, congressional and regional elections, citing glitches in the electronic balloting system. Thursday’s delay gives President Hugo Chavez’s main challenger, a former state governor named Francisco Arias Cardenas, more time to try to reduce the President’s fifteen- to twenty-point lead in the polls. The Supreme Tribunal of Justice suspended the balloting, citing a lack of credibility and transparency because of the technical difficulties. The court instructed the legislatures to set a new election date and prohibited campaigning until it is announced.
