Here’s something interesting about the State of Georgia that — despite the fact that I’ve lived here for fifteen years — I just learned today.
Rather than specifying a party (or Independent) when registering to vote, and thus only being able to vote in that party’s primary, Georgia residents just register as voters. No party gets selected.
Then on primary day each few years you get to choose which of the partys’ primary you’re going to vote in… You are going to vote, aren’t you?
What’s the system in your state?
