Voter Registration
Party Affiliation
Do I have to declare a political party when I register to vote? Why can't I vote a split ticket in the primary?

Voters are not registered by political party in South Carolina. On primary election day, the voter may choose a political party with whom to participate.

Once a party choice is made, for that primary election, only one ballot may be voted. The primary is only a nomination process for a political party; whereas the general election a voter may split the ticket among various political parties and candidates of their choice.
