Basic book/TV show knowledge required, but plots do not determine who was involved in the election - it doesn't matter if they're supposed to be dead etc.
W = Winner (there is only one), C = Candidates, V = voters. In the game, to 'stand' means to stand for election, so this includes both candidates and the winner. Anyone who didn't stand for election is a voter. Anyone not eligible did not stand for election, and is therefore a voter.
