Yes, but very limited. Basically, only if you're disabled, old (basically the retired), or temporarily residing elsewhere (aka rich people with multiple homes).
Who is entitled to vote absentee by mail?
- Any person who is temporarily residing outside of their county of residence, and the ballot must be mailed to an address outside the municipality.
- Any person who has a temporary or permanent physical disability and who, because of such disability, is unable to vote in person without substantial hardship to himself, herself or others, or whose attendance at the voting place could reasonably cause danger to himself, herself or others.
- The parent, spouse or dependent of a person with a temporary or permanent physical disability who is hospitalized outside of his or her county of residence or more than fifty (50) miles distant from his or her residence, if the parent, spouse or dependent will be with such person on election day.
- Any person who is sixty-five (65) years of age or older.
- Any incarcerated individual who has not been convicted of a disenfranchising crime. Residency of incarcerated individuals is determined by the residence of the person prior to his/her incarceration.
