There are barriers for the homeless to register to vote. They may lack a place of residence, a mailing address or a form of identification.[3] Having a place to live is not a prerequisite to vote. As argued in 1984 case Pitts v. Black, people are eligible to vote even if they do not live in traditional accommodations.[4] The cost of transport to the ballot station is also an obstacle for the homeless to vote as well as the feeling of being politically disenfranchised.[5]
For registration purposes, homeless people can use the mailing address of shelters or religious institutions or post offices. Each state has its own voter registration requirements.[6]
