Is that because of 'ordinary' class-divided politics (poorer working class suburbs against relatively more affluent countryside) or is it for more, er, typically South American reasons?
I would argue that peronism tends to do well in places which have lower income levels, less education credentials, less-developed regions, etc. The typical places where the left wins in other nations. The opposite had happened with the UCR historically, and now with Cambiemos. This doesn't necessarily mean that peronists are all leftist (they don't came from a socialist tradition as social democratic parties in europe) and non-peronists are all right-wingers, but in general terms, i would say they are, at least in economic policy.
