Buenos Aires lawmaker and Argentina's current presidential frontrunner Javier Milei holds a caravan with supporters ahead of the October 22 elections. Greeted by an adoring crowd, the 52-year-old economist and fiery libertarian signs copies of his book, autographs mock $100 bills with his face printed on them and chants against fellow politicians he calls the "caste." Milei has proposed dollarizing the economy and imposing strict austerity measures. He says climate change is a lie and that he plans to get rid of the central bank, ban abortion and make it easier to buy guns. IMAGES
