The concept of electoral accountability is foundational to democratic systems. But can family ties undermine this core mechanism? While previous research has shown how factors like electoral competition, polarization, and access to information shape accountability, it has often overlooked the impact of politicians' connections and familial ties. We argue that politicians embedded in large family networks benefit from unconditional electoral support from their relatives, reducing their incentive to perform well in office. Employing a two-way fixed effects model and a regression discontinuity design in Italian municipal elections from 2000 to 2020, we find that mayors from larger families exhibit poorer economic performance. Crucially, our analysis further shows that large-family mayors are not electorally punished in the following elections for their poor performance. These findings reveal how family ties can alter politicians' incentives to perform and undermine accountability in democratic systems.
