A surprise surge by the Argentine opposition candidate on Sunday drove the presidential race to a runoff, the first in its history, with the two main candidates locked in a near tie. With 97 percent of the vote counted, Daniel Scioli, the ruling party candidate, held 36.9 percent, while Mauricio Macri of the opposition held 34.3 percent.
