Today is Election Day in the United States. It happens on a Tuesday is because in 1845, when Congress picked “the Tuesday after the first Monday in November” (seriously), the country was largely an agricultural society. It might take all day for people to get from their farm to the nearest polling place. They wouldn’t do it on a Sunday, because that was the Sabbath. Wednesdays, Fridays, and Saturdays were market days in various places. Presumably everyone hated Mondays even then. So they went with Tuesday. It doesn’t make much sense any more, because people work on Tuesdays. Other countries either hold elections on the weekend, or make Election Day a holiday so voters have the day off. Somehow we’re still stuck with this wacky system.
Think about the topics that have come up in the current election cycle. How would those translate into your fictional world. If some form of democracy exists, how are elections organized? When are they held? Are there issues that people are voting for, that are hotly contested? Even if another form of government exists in your setting, do the people have a voice in any way? Are their issues of corruption? Does the government have rallies to inform people of policy changes? Are their protest movements that express their displeasure with what the government is doing?
