Around five million citizens of voting age in the United States can't vote, due to the fact that they have a felony on their record. These people have served their time, but are still denied the vote. If we are truly a participatory democracy, we should allow all adults in our society the right to vote, regardless of their past criminal history. As far as I'm concerned, even if you're still in prison you should be able to vote. Just because you have broken the law doesn't mean your voice shouldn't be heard.
