This article intensely analyzes the voting practices of three women from the working class in ethnically diverse neighborhoods in 2017. Thanks to observations in the neighborhood before, during and after the voting, the localized analysis within a very segregated neighborhood renders their contrasted votes within the very conditions of their production, revealing the weight of class and gender membership and race-related social relations. Although these three women, who live in the same residential context, vote for very diverse candidates, politically speaking (from the National Front to the Socialist party), in all three cases, their positions within the local working class, their female condition, their relations inside their family, their ethnic and racial (and religious) characteristics all say something about not only their statistically improbable electoral mobilization, but also the variability of their voting practices, which tends to be related to differentiated and conflicting social relations within the neighborhood.
