Javier Milei is a right-wing populist who admires former U.S. President Donald Trump and made a name for himself by shouting against Argentina's “political caste” on television.
Milei is an idiot, but I can't blame Argentinians (much) for voting for him. What other choices do they have that they haven't tried several times already, each time with disastrous results.
It would be interesting to know how many of the votes he'll get are actually votes "for him" as opposed to "anything but the established parties".
That's actually the best summary I've read for a long time.
Having said that, besides Milei being a right-wing misogynystic asshat, linking the peso to the dollar might actually do the country's economy a lot of good in the long term. It has been tried before - sadly unsuccessfully because the rampant corruption in other places more than negated the positive effects, so Milei's success there probably depends on a) whether he actually does what he's promising to do, b) whether the new government actually will be less corrupt than the current and previous ones (though being any more corrupt than the Kirchner clan is going to be super hard), and c) whether the people will support the changes long enough once they realize that it means they too will get less subsidies and government hand-outs.
