Misdemeanor Disenfranchisement? The demobilizing effects of brief jail spells on potential voters

This paper presents new causal estimates of incarceration’s effect on voting, using administrative data on criminal sentencing and voter turnout. I use the random case assignment process of a major county court system as a source of exogenous variation in the sentencing of misdemeanor cases. Focusing on misdemeanor defendants allows for generalization to a large pool of people, as such cases are extremely common. Among first-time misdemeanor defendants, I find evidence that receiving a short jail sentence decreases voting in the next election by several percentage points. Results differ starkly by race: White defendants show no demobilization, while Black and Latino defendants are substantially demobilized. Black defendants show a turnout decrease of about 13 percentage points due to jail time. Evidence from pre-arrest voter histories suggest that this difference could be due to racial differences in who is arrested. These results paint a picture of large-scale, racially-disparate voter demobilization in the wake of incarceration.
