Hi OWG,
I agree that there shouldn't be any reason, if someone hasn't participated in an election for several years, that there can't be some sort of check to see if they are still around. I've moved dozens of times in my life to several different cities and states. Calling or notifying elections officials of my not being in the district any longer was never on my list of things to do. I imagine that my name may be on a half dozen voter registration rolls around the country. I would have no problem with any of those districts removing my name.
I imagine that the majority of these 200,000+ people have moved out of the area, or may even be deceased. So, I agree, there needs to be a point, where elections officials make an attempt to contact a registered voter who hasn't voted in 6 years or so, with a notification letter requesting a positive response. If no response, then take them off the rolls. If they come back to vote 10 years later, then re-enroll them. A list of dropped names could always be available for say the next 10 years so that if someone did return, their validation to put them back on the active rolls would be somewhat easier and could be done on the spot with proper ID.
God bless,
In Christ, ted
