Trump and Haley Will Face Off in South Carolina. Here’s What to Know.

The foursome of early Republican nominating contests will soon come to a close with the South Carolina primary, following the Iowa caucuses and New Hampshire primary last month and the Nevada primary and caucuses this month.

Here’s what to know.

When is the South Carolina Republican primary?

Saturday, Feb. 24.

Who can participate?

South Carolina has no formal party registration, so registered voters can participate in the primary regardless of whether they identify as Republicans, Democrats or independents.

However, if you voted in the Democratic primary this month, you can’t vote in the Republican one, too.

How can I vote?

The polls will be open on Election Day from 7 a.m. to 7 p.m. (You can find your polling location here.) You can also vote early from now through Feb. 22 — except for Feb. 18-19 — but your early-voting location may be different from your Election Day polling site, so be sure to check here.

Either way, you’ll need to show photo identification.

Some South Carolinians can cast absentee ballots by mail. You can find out whether you’re eligible for that here.

Unfortunately, if you’re not already registered to vote, it’s too late to do so for this primary; the deadline was last month. But you can find the information you need here to register in time for the nonpresidential primaries in June — when congressional, state legislative and local races will be on the ballot — and the general election in November.
