Prisoners should have the right to vote according to the principles of democracy. Around 2 million prisoners in the US are denied this right. While some countries and US states restrict prisoner voting, Vermont and Maine allow all prisoners to vote. The 15th Amendment states the right to vote cannot be denied based on race or past actions, but this is not applied to prisoners in most states. Advocates argue that denying prisoners the right to vote is inconsistent with democratic values of participation and that their votes could influence election outcomes.
