Insult to injury is the additional administrative burden of voter registration.

It's a database query to generate a list of eligible voters and where they can vote. Literally.

Bonus points for maintaining 50+ heterogeneous legally separated voter registration databases. Thereby maximizing the likelihood of errors. Plus every VRDB has one or more teams of saboteurs; purging eligible voters, monkey wrenching, and sowing FUD.

...it's almost as if the there's some far reaching, widespread campaign to disenfranchise voters.
