Corruption is chronic there. I traveled to Brazil with a friend , he did a mistake(not using common sense) an his camera and the bag we used with several electronic tools was stolen. He went to the police, and was beaten by the police!!
We are from Spain and he simply expected a behavior in institutions that does not exist there. In Brazil you are either rich or poor, and police protects the rich(or the highest bidder) with iron fist. They are rude and you better not resist.
Argentina by the way has Spanish and Italian "picaresca" on their veins. "Ser un vivo" and fool other people is not only ok, but something to brag around.
Electronic voting could work on Switzerland or Denmark, and even there I will only trust it for menial tasks, like what they do in Switzerland asking people opinion on the new street lights(they do it using mail!!) and so on, but never with serious things like who gets in power.
Last time I was in Argentina,there were elections, and the politicians were literary buying the vote of poor people with crumbs even renting buses for them.
