I think it's understandable why Argentinians would vote for a wackjob like this.

Argentina for the past decade has been in a terrible economic situation, and the system has no real solution for it.

No one so far, neither left nor right, had the balls to try something outside the box, nowadays economical talks by the country's political class mostly consist in ways to restructure and renegotiate the debt (which they can't pay anyways, no matter how much they shift the numbers around).

In a bizarre, twisted way this guys proposal to adopt the dollar, is probably the first "outside the box" proposal that has any form of popular approval, not because its any good (its not) but because Argentinians, especially the older generations, have a lot of nostalgia from the time the Peso was pegged to the dollar, considering it as the "golden age" of the country, which is not necessarily wrong even though that was what caused their economic troubles to begin with.

Would it work? Hell no, this guy winning would potentially throw a wrench in Argentina's foreign policy and if his stupid plan for dollarization is approved it'll fucking kill the country outright.

To me, nothing short of a revolution will fix Argentina, but given how alienated and fragmented the population is, that's not happening any time soon.
