Three voters vote over two candidates (A and B), and each voter has two pure strategies:
vote for A and vote for B.
When A wins, voter 1 gets a payoff of 1, and 2 and 3 get payoffs of 0;
when B wins, 1 gets 0 and 2 and 3 get 1.
Thus, 1 prefers A, and 2 and 3 prefer B.
The candidate getting 2 or more votes is the winner (majority rule).
