I'm one of these people, but I would never vote for a Peronist, let alone a pancake like Massa. The enemy of my enemy isn't my friend, and politically I'm not a cyrpto-fascist (Milei), neoliberal (Bullrich), or Peronist (Massa) so that's why you won't see me arguing he is the answer, even though I dislike them, because if it's Milei vs Mass I'd be voting en blanco.
Also it's important to remember the overwhelming majority of this forum skews right wing, but not the flavor Milei is, and I assume they don't agree with his policies like myself, even though I'm politically on the far left, we just all sort of collectively agree he's bad.
The case for Massa is hard for two reasons: A) He's been Superminister for a year now, and things have only gotten worse, and B) What would he be doing differently than he's doing now? Cristina has already caved and let him do a bunch of shit she normally wouldn't be okay with, such as a devaluation during election season, so his presidency wouldn't be that different.
The pitch I suppose is the devil you know vs the one you don't, which isn't very convincing. I'm actually surprised Bullrich isn't doing better than she is, she has the easiest case imo, "I'm Macri 2.0", the Macri years weren't great, but they sure as shit were better than Alberto's admin for everything from minimum wage, inflation, pensions, etc. and Milei is still an unknown quantity in the sense that there will be a lot of pain before anything gets better (if you believe in his agenda) and he won't have Congress to even implement half the things he wants to, so why not role back the clock to 2015?
Anyways, what do I know. There's only 3 guarantees in Argentine life: death, taxes, and the depreciation of the peso, regardless of who wins.
