OK Shai,
you do know something about the US constitution. the fact that some states revoke voting rights from convicts and or prisoners does indicate that the U.S. constitution allows this. otherwise those state rules would have been overturned by the U.S. federal courts due to unconstitionality. however, I don't agree with your statement that suggests that revoking voting rights of criminals is somehow anti human rights. do you think that convicted murderers and rapists should have the right to vote? I don't.

convicts who serve time in jail can lose their right to vote regardless of their crime. my "killers and rapists" example was not necessary. as for the difference between killers and "big fish" thieves, that is another subject that has to do with your definition of basic human morality.

if you want to have a conversation here, please present you arguments and refrain from personal attacks such as

convicted criminals who serve time in jail lose most of their freedoms, for a certain period of time, as punishment for their crime. why the special concern with "the right to vote "?
however, in some states convicted criminals lose their right to vote for life! in other words, they cannot vote even after they are released back to society. this is wrong and needs to be changed; but hey, no system is perfect.

answers to Mitz Petel (PJ) & Eyal Arsi,

1. the number of would be voters that can't do so because they are convicts or ex-convicts is completely negligible. and, as PJ wrote, most poor people are not registered voters and usually don't bother to vote.
2. I really hope that one day black people in America would be considered potential voters for a democratic ticket that includes a jewish candidate for vice president.
