Chile celebrates as leftist Boric elected president

The streets of Santiago erupted in celebration Sunday after leftist millennial Gabriel Boric became Chile's youngest-ever president-elect with an unexpectedly large victory over his far-right rival in a polarizing race.

Boric, 35, garnered nearly 56 percent of the vote compared to 44 percent for ultra-conservative Jose Antonio Kast, who conceded even before the final result was known.

Tens of thousands of Chileans took to the streets of the capital and other cities after Kast's concession, honking car horns in approval, brandishing pro-Boric placards, waving the flags and shouting: "Viva Chile!"

Fireworks lit the skies for hours on end.

"I’m thrilled, I am crying with joy. We dealt a blow to fascism!" pharmacy worker Jennie Enriquez, 45, said.

"I am happy because there are going to be many changes that will help the people and the working class," added construction worker Luis Astorga, 58.

Boric had campaigned on the promise of installing a "social welfare" state, increasing taxes and social spending in a country with one of the world's largest gaps between rich and poor.

Branded a "communist" by his detractors, he vowed in his first official address Sunday to "expand social rights" in Chile, but to do so with "fiscal responsibility."

"We will do it to protect our macro-economy, we will do it well... to improve pensions and healthcare," he said.

Kast congratulated Boric, who leads an alliance that includes Chile's Communist Party, "on his great triumph."

"From today on, he is the president-elect of Chile and he deserves all our respect and constructive cooperation. Chile always comes first."
