This paper appears to be the first to analyse political campaign incentives when the electorate vote at different moments before Election Day, a phenomenon known as early or advance voting. Many jurisdictions accommodate such voting by accepting mail-in ballots or by opening polling places before Election Day. Since politicians can thereby add campaign promises while citizens vote, they have an incentive to add promises valued by late-voting segments as Election Day approaches. This implies that early-voting segments of the electorate will pay higher taxes and receive lower transfers than had been announced when they voted. Late-voting segments benefit.
