The lead in Peru’s statistically tied presidential election swung from right to left Monday – leaving the country facing days, if not weeks, of uncertainty before a winner is declared. Right-wing candidate Keiko Fujimori held an ultra slim advantage Monday morning, but by the afternoon, leftist candidate Roberto Sánchez had eked out a minuscule lead – two-tenths of a percentage point, with 94% of votes counted. Election officials foresee additional moves in the top spot as final votes roll in.
