The article examines the meaning of migrants’ (dis)enfranchisement within democratic polities, focusing on ideas of political authority and agency derived from democratic theory. Building on the notion that democratic voting represents a mutual and second-personal exercise of authority, the article argues that the disenfranchisement of migrants signifies their exclusion from agential authoritative relationships in politics, and ultimately, from a quintessential democratic mode of political agency. We recall some of the principles for expanding voting rights and acknowledge that there may be reasons in favor of exclusion. However, we highlight how any such exclusion (re)shapes the political relationships instantiated in the practice of voting. While we rebut the challenge of “voting fetishism,” we conclude by discussing how alternative forms of political participation for migrants, though important, cannot compensate for the unique impoverishment of political authority and agency that disenfranchisement specifically incurs.
