Electoral fraud: the abstentionist census
Imagine that, unintentionally, you want to commit some kind of electoral fraud and, for that, you need to introduce votes into the ballot boxes of people who have not gone to vote, for example, voting by mail on their behalf.
Well, that information — who votes and who doesn't — along with a history, is in the hands of the parties who, through their poll watchers, keep track of who votes and who doesn't.
What could it be used for? From mobilizing people you know should vote but haven't shown up, by calling them, something that in principle is not fraud,
to taking advantage of moments when no one is present to vote in the ballot box for those people, for example, during lunch breaks.
Or even voting by mail on their behalf.
All this could be mere speculation, but if it is possible to do... why not do it? Let's remember the government we have and what they have already done; the idea is for the electoral system to be proof against these situations.

2014-05-24 A legal loophole allows parties to identify which neighbors abstain
Party poll watchers and proxies at polling stations have access to the electoral roll and mark throughout the day who votes and who is absent.
The Electoral Board requires parties to dispose of the list, but no agency oversees compliance with this order; the Data Protection Agency has not yet issued any report.
The mechanism opens the door to identifying by name and surname who has not gone to vote, secret and sensitive information, especially in small municipalities.
