Voting & Fairness
Who "should" win an election? It depends on how you count. Compare voting systems on the same ballots, meet Condorcet's paradox and Arrow's impossibility theorem, watch instant runoff punish a candidate for gaining support, redraw districts to flip an election, see how dividing seats can go strangely wrong, and measure who really holds power.
