Just noticing the differences...
Somebody living in the US over the last 40 years wouldn't really have a way of knowing that there'd ever been anything you might call a legitimate political left in the world,or even legitimate populists, especially when the dems go to such lengths to villify and demonize every real populist who ever comes down the road and, by that, I mean the Sarah Palins and George Allens of the world.
Closest thing to a US category for the Perons would be populists. A US citizen would figure them for leftists but the term doesn't really work for them. A US citizen would hear a term like 'descamisado' and figure it meant somebody who couldn't afford a shirt i.e. a member of some dem voting block while it apparently meant guys who took shirts off to work in the Argentine sun i.e. the people doing the heavy lifting in the place.
As near as I can tell and despite anything they might have not gotten right in the time they had, the Perons appear to have been totally straight up. Several of the things you notice would only bother somebody unfamiliar with the setting. They played hard-ball politics, but so did everybody else at the time. The expensive wardrobes bothered American reporters; I would guess that Argentines figured that a guy like Peron who had a woman like that and DIDN'T
dress her as well as he did would be some sort of an asshole.
