Pedro, and you don't even need to go that far in time. I've met younger than me ( although I'm not that soooo young any longer) who, so careless about politics, told me they voted for PSD or PS because their parents voted for them. What scares me is that these people are, allegedly, educated, which tells you a lot about the educational Portuguese system still so biased against humanities... ( yes these people were on the other side of learning)
