“…The results are in line with previous research finding that marrying a voter increases one's likelihood of voting (Stoker and Jennings, 1995;Bhatti et al, 2018). Theoretically, the results support the idea of a social mobilizing effect (a spill-over effect, a companion effect, or a contagion effect) (Gerber et al, 2008;Nickerson, 2008;Fieldhouse and Cutts, 2012;Rolfe, 2012;Sinclair et al, 2012;Bhatti et al, 2017) and a social demobilizing effect (Partheymüller and Schmitt-Beck, 2012) in the case of marriage and cohabitation. Moreover, showing that both selection into, and the social influence in relationships, matter for who participates in politics, the paper adds valuable insights to the longstanding debate on selection versus social influence (Kandel, 1978;Huckfeldt and Sprague, 1987;Jennings and Stoker, 2005;Alford et al, 2011).…”
