For professors and teachers

Your students read about campaigns. Here they run one.

Campaign Margins turns campaign strategy into decisions your students actually make, built from the same research you already assign. Most games are single-player and take under half an hour, easy to assign as homework. Who's Your Mayor? is multiplayer, built to run live in class as competing teams. The game puts students in the decision. Your debrief is where the learning lands.

Why it works in a course

Why professors assign it

These are real strategy simulations, not quizzes or points added to a reading. The mechanics come straight from the research, so the decisions they force are exactly the ones worth debating in class.

Grounded

Built on the research you teach

The mechanics come straight out of the literature: Kalla and Broockman on the limits of campaign persuasion, Downs on spatial positioning, Herrnson on the campaign for resources, the incumbency research. Students do not just read the findings. They run into them.

Discussion

It creates decisions worth debating

Every game forces a real tradeoff: where to spend a fixed budget, which coalition to court first, when to go negative and what it costs in November. Students arrive at your debrief having already taken a position they have to defend.

Zero setup

Frictionless to assign

Free, in any browser, no accounts, no installs, no IT ticket, under half an hour. You send a link. There is no software to approve, no student data to collect, and no per-student fee to justify to anyone.

In the room

How to use it in class

Who's Your Mayor? is the multiplayer game, the one that turns a lecture hall into a live campaign with competing teams. The single-player games slot in around it: assigned as homework, played in class, or built into a written assignment.

Live multiplayer · Who's Your Mayor?

Turn the class into competing campaigns

Put one screen on the projector and split the room into campaign teams. Every student joins from their phone, laptop, or tablet. The teams run the same mayoral race at the same time, courting the same neighborhoods, chasing the same endorsements, deciding when to spend and when to hold.

They apply coalition strategy and resource allocation against each other, live, then watch it resolve on election night. Afterward you debrief who won, and why. It is the difference between reading about strategic interaction and being on the wrong side of it.

Pre-class assignment

Assign a solo game before the lecture. Students arrive having already decided where to spend, which coalition to court, and when to go negative. Your lecture becomes a debrief of what they did and why.

Turn it into a written assignment

Have students submit a short strategy memo after they play: what they decided in week two, what it cost them, and what they would do differently. Every student has a concrete campaign to write about, and no two of them are the same.

Academic grounding

The research it's built on

The mechanics were built from the findings, so the strategy that works in the game is the strategy the research says works.

Kalla and Broockman
(2018)
Across forty-nine field experiments, campaign contact showed almost no persuasive effect on candidate choice in a general election. Changing minds is the hard part, and contact rarely does it. The ground game in The Mayor and The Primary models exactly that distinction: canvassing returns depend on who is actually gettable in a given neighborhood.
Downs
(1957)
Spatial voting and the median-voter constraint. The Primary makes the primary-to-general tradeoff a decision you feel, not a diagram. Every platform stance carries a primary-base effect and a November cost.
Herrnson
Congressional Elections
The standard text on congressional campaigns, built on the argument that successful candidates run two campaigns at once, one for votes and one for resources. It shapes The Primary's convention and coalition math: an endorsement is not a press release, it is a network, an organization, and a voter list.
Incumbency advantage
Erikson (1971), Mayhew (1974)
One of the most replicated findings in the field. The Mayor builds the incumbent's head start into the board: a name-recognition lead, a visible war chest, and the ability to answer your moves with money.
Direct democracy
Elisabeth Gerber (1999), Matsusaka (2004)
Who backs a measure shapes how voters receive it, and the kinds of groups behind it are not equally effective. The Initiative makes coalition sequencing the core problem: lock in the right endorsers before the opposition hardens the undecided.
