Bolivians head to the polls Sunday for elections that could spell the end of the long reign of the leftist Movement Toward Socialism party and see a right-wing government elected for the first time in over two decades.The election is one of the most consequential for Bolivia in recent times – and one of the most unpredictable. Even at this late stage, a remarkable 30% or so of voters remain undecided.Polls show the two leading right-wing candidates, multimillionaire business owner Samuel Doria Medina and former President Jorge ‘Tuto’ Quiroga, locked in a virtual dead heat.The elections are taking place amid the country's worst economic crisis in four decades.
