That's what makes the case here so interesting because people know what the new govnerment is and what it will do, but voted it back in regardless.
I think here people do not vote based on their belief or historical data, partially because they are not current on those and partially because it doesn't bode well with them.
Of course, none of us know everything about what happened here or home, and even very informed people (i.e. 'experts') can come to radically different conclusions based on the observation of the same historical period.
I wonder how many people voting peronista have ever seen anything not peronista and not a military dictatorship. And I can say that if I had to pick between a blood-shedding military regimen and a peronista government, I'd pick the latter, too.
Macri, imho, failed to really change things - he failed to offer a third, more balanced way. He named his party Cambiemos, but he didn't change the country... he simply tried to steer the country in a different direction by playing too safe.
So we're back to peronism.
