Recent studies provide conflicting accounts of whether indirect contact with the American carceral state mobilizes. We revisit this controversy, using a large national survey of Black Americans that includes a novel measure of social connections to people with felony convictions to examine spillover dynamics. We find that while ties to the carceral state are widespread, the impact of these connections on participation is moderated by the severity of state-level felony disenfranchisement laws. In states with the most severe disenfranchisement policies, close ties to people with felony convictions increase both voting and nonvoting participation, but there is no effect in states with more moderate laws. The findings suggest that surrogate participation may be at work, whereby formally removing the rights of one group in a way that seems extreme or unjust mobilizes those close to them, and highlight the importance of policy context on political behavior.
