Research / Campaign Casebook

The Campaign Casebook.

One page for each election: what public data show about how candidates and campaigns use social media, and what the same data cannot show. Eighteen elections in fifteen countries, each read on its own terms.

The Casebook describes the data. It does not rank countries, parties or campaigns, and it does not claim that any account or message changed a vote.

How to read it

Three rules for every case.

Public social media data are patchy, collected for different purposes and rarely comparable. The Casebook keeps cases apart so that a gap in one is never filled from another.

Rule 1

One election, one page

Each case is built only from that election's own files. Nothing is added, averaged or ranked across cases.

Rule 2

Source and limits shown

Every chart names its source file. Every case lists what its data cannot show, such as posts, reach, dates or votes.

Rule 3

Patterns need three cases

A pattern needs at least three cases that agree. Fewer is only "emerging", and conflicting results are shown as "varies".

The cases

Eighteen elections.

Choose an election to open its page below. The tag on each card shows how deep the data go: some hold posts, some only counts, some only a list of candidate accounts.

Selected case

Across cases

One comparison that can be tested.

Few questions can be asked the same way in several elections. This one can: whether winning candidates are more likely than others to have an X account. The result shows who has an account, not that having one helps win.

The Casebook shows what public data can and cannot tell us about campaigns. Polity Lab's election data and strategy work start from the same discipline: say what the evidence supports, and where it stops.
