Should prisoners be given the right to vote?

Yes:Disenfranchisement increases prisoners sense of separation from society. Therefore increases anti-social behaviour.Conversely, enfranchisement (see, e.g., Tocqueville) encourages citizens to look beyond their own interests to the interest of society. Therefore encourages pro-social behaviour.A fundamental right as a citizen is to have a say in who governs. If we deny the right to vote, we deny that prisoners are citizens, therefore why do we have the right to imprison them?
No:They have demonstrated that they are not fully capable members of society. We are therefore justified in removing some of the rights of full capable members of society, including the right to vote.The prisoners' vote represents a dangerous voting base. It might encourage niche politicians to pander to the interests of prisoners.Prison is supposed to be a punishment – part of that punishment is the removal of the right to vote.
