What Happened: Alberto Fernandez, the main presidential candidate of Argentina's opposition, received 47.7 percent of the vote in a primary election on Aug. 11, while incumbent President Mauricio Macri scored 32.1 percent, with 95 percent of the votes counted, the BBC reported Aug. 12.
Why It Matters: Argentina's primary vote serves as a test ahead of October's general election, and the wide margin between Fernandez and Macri suggests widespread support for the opposition candidate. If Fernandez secures at least 45 percent of the vote in October's general election, he will become the country's next president without a runoff.
Background: Voting in Argentina's primaries is mandatory, making them a clear indicator of voting tendencies within the country. If no candidate secures at least 45 percent of the vote on Oct. 27, a runoff will occur on Nov. 24, with the winner to assume office in December.
