Explain the relationship between citizenship and the right to vote

A voter is a resident who votes. In many states, it's conceivable to tell on the off chance that you've voted in past decisions albeit clearly not who you voted in favor of. The gathering political machines do monitor this in states where these records are freely open and in this way can tell "voter" from "nonvoting resident". 
A few subjects are not permitted to vote. The most widely recognized reason is age, as those under 18 are not by and large permitted to vote, but rather are still natives. Others incorporate having been settled as rationally bumbling and having been sentenced a lawful offense.
