This paper argues that voters have duties of political justice to rectify imperfections in the democratic process, specifically unjust exclusions from the suffrage. The basis for such duties is that voters benefit from unjust suffrage exclusions and therefore have special duties to rectify them. In order to show that these duties apply to all voters, the paper explains the relevant sense in which all voters benefit from unjust exclusions from the vote. Next, the paper specifies the claim that benefitting from injustice grounds rectificatory duties, how this applies to voters, and how they can discharge their duties through the vote, either by restituting electoral injustices, compensating their victims or by disgorging the benefits they unjustly derive from electoral injustice.
