Argentine voters are sharply divided ahead of a historic and uncertain presidential election on Sunday, with some saying they might not make up their mind until they reach the ballot box, opening up the potential for last minute drama. The vote is a tight three-way race between frontrunner radical outsider Javier Milei, ruling Peronist Economy Minister Sergio Massa and center-right former security minister Patricia Bullrich, all offering starkly different visions for Argentina. Libertarian economist Milei is in pole position to win, though would likely face a second round.
