There is a check via an ID scanner before going into the voting booth that ensures you’ve only voted once. No one know who I voted for either. The only downside to this is that if you haven’t updated your ID when changing address, you would have to go to the district on your ID to vote. This somehow makes sense since for parliamentary elections, for example, you have different candidates for different districts.
Adapt or die. They did not adapt. Not to mention corporate greed, expecting infinite growth to be sustainable. And then the blue collars are the ones affected the most.
