Bolivia is preparing for its first-ever presidential runoff, a vote that ends years of one-party rule and gauges the surprising rise of a centrist senator. Campaigning for the initial round ended only a day ago, yet the nation’s political machinery is already pivoting to a second vote that could redefine its future.

Bolivia’s presidential election will move to an unprecedented second round after a surprise first-place showing by centrist Sen. Rodrigo Paz. Although he outpaced right-wing rivals in Sunday’s vote, Paz fell short of the majority needed for an outright win, forcing the nation’s first runoff between a centrist and right-wing field.
