South Carolina has open primaries, but you are only allowed to participate in one party’s primary (this affiliation lasts only for primaries, except in the case of a runoff where you must vote the same as you voted in the primary).
South Carolina does not have registration by party. In primaries, you can vote in only one party’s primary.
