Suffrage

I have been thinking about the idea of universal suffrage.  And how it is a complete fallacy.  The truth is there is very restricted suffrage in the US.  From minors to, immigrants, those who are insane and so forth suffrage is a privilege not a right and certainly not universal.  There is a restriction on voting because on individual's vote affects everyone as a whole.  And it is in this light that I would like to put out there that person's who commit felonies should have their privilege to suffrage removed.  I mean if their vote is made to affect everyone as a whole, haven't they proved their inability to do so for the good of others, i.e. they have committed a felony.  As above voting is not a right but a privilege give by the whole to a few, thus I believe that privilege should be removable.
