The proliferation of migrant social media campaigns calling for a 'Yes' vote in the Irish Marriage Equality referendum (May 2015) raises new questions about the conventions of political participation and non-resident citizenship rights. Via a discourse analysis of these campaigns, this article shows how the algorithmic agency of social media combines with the political agency and affective identifications of campaigners to shape the terms of non-resident citizen claims for enfranchisement and sexual citizenship rights. The article argues that despite their novel political tactics, the central campaign discourses of (im)mobility (leaving/staying-put), connectivity (active engagement) and ongoing stake in an inclusive homeland are underpinned by conventional democratic criteria for enfranchisement. The article addresses how these discourses intersect with state and business regimes of mobility and connectivity to produce a particular ordering of citizenship. It also points to those emergent practices and norms of political participation generally, and of non-resident citizenship in particular, that are foregrounded by these campaigns.
