No partisan voter registration in Mississippi 
I'm always confused by this - does this mean you CAN'T register with a party or that you just have open primaries?
Both.
You can't "register" with a party in the sense that there's no way to become associated with a political party besides joining your local county executive committee and paying membership dues.
And all primaries are open, and I regularly vote in both Democratic and Republican primaries depending on the election in question. Typically vote in Democratic primaries at the county/local level and GOP for statewide offices. That's why open party registration is so popular in the South - it allows for that local Democratic core that's been present since Reconstruction to stick around because of people like me.
