In NC when you get an ID or a license it is mandatory for them to ask 2 questions: would you like to register to vote? Register for which party? Unfortunately how the party system works, you can't just merely auto register to vote...as we seen this year in the democratic primaries you must register as a democratic in order to vote democratic in their primary.
