Chile’s Presidential Election Upends Centrist Legacy

SANTIAGO, Chile—Two antiestablishment politicians from opposite ends of the political spectrum have advanced to a runoff vote to select Chile’s next president, deepening the political instability in Latin America’s most affluent country.

The first round of voting on Sunday upended the future of a centrist political system that over the last three decades made Chile a global model for free trade and a magnet for foreign investments while slashing poverty.
