At this point I'm not sure what you're saying considering the context is that they're replies to my posts.
The one measure restricting voting I can kinda get behind (but not the way it usually gets implemented which is straight voter-suppression) is purging the rolls. Usually they do it with elections coming up to try and deter some elements from voting and that's ridiculous. If you want to remove no-longer-valid entries, the time to do it would be not long AFTER an election. Probably send out letters in the six months prior soliciting confirmation that the registrant is still active at their listed address and warning that due to inactivity, discrepancies, apparent duplication, etc. that they will be removed at the end of the current cycle and would have to re-register to vote in subsequent elections without it. I wouldn't have a problem with a system where registration needs to be renewed periodically like most licenses either.
