CMV: The right to vote should never be removed from a current citizen.

(Edit: This has become much more of an involved conversation than I expected.  I am trying to respond to as many points as I can, but please be patient and feel free to respond to each other as well!  I am somewhat disappointed not to see any deltas from someone NOT the OP.)

The only ways I know of that you can be disenfranchised (permanently or temporarily) in the US are:
1) Crime
2) Debt
3) Disability
4) Place of residence

Of these, I can’t see any legitimate reason for them.  

In the cases that have potentially understandable reasoning (e.g. complete mental incapacity) would seem to have such a small impact on an election as to be negligible.  A couple of non-vetted sources estimate numbers on the scale of thousands to a couple million of Americans…less than 1% of the general population by the most recent census.

The remainder of cases are by definition reasons I don’t even see the potential for legitimacy.

To be clear, I am not referring to practices of voter suppression (preventing legal voters from legally voting).  I am referring to legally stripping a voter from their legal right to vote.

Edit: I have agreed that severe mental incapacity would be a reasonable exception.

Edit: I have some homework to figure out the difference between depriving rights such as lift/liberty (capital punishment/imprisonment) and voting.

Edit: There are methods of voter suppression that amount to disenfranchisement.  In the interest of staying on topic I am avoiding encouraging discussion in that grey area and staying in clearcut "officially removed right to vote".

3. Mental immaturity is reason why we don't allow children to vote. Same can be said for disability.

4. Place of residence shouldn't effect federal elections but certainly would void your right to vote in state elections.
