LA PAZ, Bolivia — Exit polls issued early Monday showed Bolivia's socialists taking a seemingly insurmountable lead in the country's bitterly fought presidential election, a result that, if confirmed by the official tally, would amount to a massive popular rebuke of the right-wing forces that drove the left from power a year ago.

 

Sunday’s much-delayed election was a do-over of last year’s contest. That vote ended with longtime socialist President Evo Morales fleeing into exile as opponents alleged electoral fraud and supporters decried a “coup.”
