Voting rights for individuals convicted of a felony vary widely by state. In ME and VT voting is still permitted, including while incarcerated. In 23 states (CA,CO,CT,HI,IL,IN,MD,MA,MI,MN,MT,NV,NH,NJ,NM,NY,ND,OH,OR,PA,RI,UT,WA) those with a felony conviction are unable to vote while incarcerated, while in 15 (AK, AR, GA, ID, KS, LA, MO, NE, NC, OK, SC, SD, TX,WV, WI) they also are unable to vote until the completion of the sentence (including probation or parole). In 10 states (AL, AZ, DE, FL, IA,KY, MS, TN, VA, WY ) individuals can lose their voting rights indefinitely for certain felony convictions or require additional steps or time to restore their right to vote.
In MO, individuals on probation or parole from a felony conviction are prohibited from voting (RsMO §155.133). Legislation proposed in the 2025 session would have restored voting rights to individuals on probation or parole, except for those who had committed a crime related to voting (HB 617). As of May 2025, there were approximately 57,000 people under MO Department of Corrections (DOC) supervision (probation or parole) following a felony conviction (Figure 1, Supplementary Table 1).
