“This one’s for all the marbles.” From schoolyards to casinos to championship games, it’s a pulse-quickening phrase meaning the stakes are incredibly high. Across North America, winner-take-all elections often work the same way: everybody who voted for the candidate or party with more votes than anyone else, even if not a majority, gets a seat at the table. Everyone else? They’re out of luck.

But elections don’t have to be a zero-sum game. Around the world, countries, states, and cities are opting for proportional representation methods, which ensure legislative bodies look like the people who elected them. When winning 40 percent of the vote means winning roughly 40 percent of the seats, everyone gets their fair share, and more voters feel they’ve won the representation they deserve.

For the hundreds of millions who have never known anything but bitter all-or-nothing contests, from US Congress down to local councils, it can be tough to envision a better way. That’s why Sightline put together an, ahem, *marble-ous* video to show how proportional representation gives voters real choices among candidates and parties they actually like—unlike the “all the marbles” approach.
