Abstract In this article, I offer a novel account of why compromising in politics is likely to involve the kind of politically admirable but morally wrongful behavior at stake in the dirty hands thesis. On the view I defend, politicians do not dirty their hands just because they compromise on matters of principle. Rather, when forging a political compromise, negotiators can either comply with the requirements of ethical compromise-making or abide by the special obligations they have to their representees, but will struggle to satisfy both demands. As a result, subsequent to such compromises, residual moral claims about how the compromise was negotiated will almost inevitably emerge and compromise-makers will not be able to explain their conduct in a way that can cancel these grievances. It is in this sense that forging political compromises can be “dirty” even if choosing to compromise is the politically responsible thing to do.
