The Senate is perhaps the most powerful body on r/SimDemocracy, at least, it is the most important one. The Senate is the body that passes, abolishes and amends 'Acts', or laws which govern the subreddit and server.
A new senate is assembled every two weeks. Anyone can run for senator as long as you are not an Executive Officer and you run by simply announcing that you are running in the "Call for Candidates"
The candidates are then elected directly by the citizens via bloc score voting, where:
Users score the candidates however they wish from 0 to 5,
The candidate with the highest average score gets a seat, and the candidate with the next highest average score gets a seat, and so on until every seat is filled.
There is also a simulated 'automatic runoff' system. If given two candidates with the highest averages, the one rated higher than the other on the most ballots wins.
The amount of Senate seats vary every election, and are pre-determined by a mathematical formula. It isn't necessary to know, but if you're curious you can find it here.
Once a new Senate is assembled, they vote for a fellow Senator to become the Speaker of the Senate (SoS).
