Do Americans realise how absolutely insane the very concept of “purging a voter registration list” is? You have to *register to vote*? What are you even talking about?
Are you a citizen? Then you should automatically get a vote. There isn’t anything to administer. You live there. The government serves you; not you it. Voting isn’t supposed to be a privilege, or reward.
The obvious abuse vector that any system other than “all citizens vote” becomes is astounding.
