Election promises are a mainstay of contemporary politics. Governments cite kept commitments as proof they can be trusted, while oppositions pounce on any failure to deliver.
But beyond the politics, campaign pledges are also central to representative democracy. They telegraph what to expect from a party in government and create a moral obligation for it to follow through.
Democratic governments across the globe fulfil, on average, roughly two-thirds of their promises, but most voters believe it is far fewer. Since voters will punish governments for breaking promises, it’s vital they have accurate information on their government’s record.
