BUENOS AIRES, Argentina (AP) - The legendary Colón Theater in Buenos Aires became the stage for a display of Argentina's deep political divide as right-wing presidential candidate Javier Milei encountered both jeers and applause from the audience during a performance of "Madama Butterfly" on Friday evening, just one day before the highly anticipated runoff election.

Videos circulating on social media captured the contrasting reactions of the audience towards Milei, who was seated in the front row of a box with his girlfriend. Some attendees can be heard chanting insults, accusing Milei of being part of the country's past dictatorship. Milei has controversially downplayed the extent of Argentina's military rule from 1976 to 1983, disagreeing with human rights organizations' assessments of the number of victims.

Notably, a few orchestra musicians played the "Peronist March," associated with the political party of Milei's opponent, Economy Minister Sergio Massa, further highlighting the politically charged atmosphere within the theater.

However, other videos shared by Milei on social media showed sections of the audience applauding him and requesting photographs. Journalist Luis Novaresio, who was present at the theater, described the scene as unprecedented, refuting earlier reports suggesting that Milei had been asked to leave. Novaresio confirmed that Milei stayed until the end of Giacomo Puccini's opera.

Milei, known for his admiration of former U.S. President Donald Trump, has been vocal in attacking what he perceives as a corrupt political elite in Argentina. He has proposed reducing the size of the state and addressing soaring inflation, which has reached triple digits during Massa's tenure as Economy Minister.

The controversial candidate has generated passionate opposition from various sectors of society, with detractors viewing him as a threat to democracy. Massa has cautioned voters that electing Milei would lead to the dismantling of public education, healthcare, consumer subsidies, and welfare programs. Milei, however, has denied these claims.

As both candidates have entered a campaign blackout period, no further campaigning is allowed until after Sunday's vote. Milei's presence at the Colón Theater, whether intentional or coincidental, thrust him into the limelight on a grand stage, with many attendees promptly posting videos of the event on social media.

Reacting to the performance of "Madama Butterfly," Milei shared his thoughts on social media saying, "What a beautiful work Madama Butterfly," followed by the letters "XD" signifying laughter.

Sunday's anticipation builds as Argentina awaits the outcome of the divisive presidential runoff, with the performances at the Colón Theater serving as a snapshot of the country's stark political polarization.
