My hypothesis is that those who are ill informed, on drugs or alcohol, or fail to register due to lack of interest are not necessary or even desirable as part of the body politic.   If that means they are unrepresented, so be it.  

I also believe that you have a right not to vote just as you have a right to vote.

'Noblesse oblige' worked fine when there was a nobility who aspired to it.  I have seen little historical evidence of that attitude in those selected to lead by the voters in this country.  At best, the leaders have tried for honesty in office.
