Welcome!
Welcome to 538's live blog of the South Carolina, Maine, North Dakota and Nevada primaries! The major action tonight is all on the GOP side, where we're tracking competitive primaries for U.S. House seats, a Nevada Senate seat and North Dakota's governor's mansion. Here's a quick rundown of what to expect.
First polls close South Carolina at 7 p.m. Eastern, where tonight's GOP primaries are tantamount to election in three solidly red seats. Next up is Maine, where polls close at 8 p.m. Eastern and voters will decide which Republican will try to unseat Democratic incumbent Rep. Jared Golden in a red-leaning district. Polls will also close at 8 p.m. Eastern in most of North Dakota, where the GOP primaries will effectively determine the state's next governor and at-large U.S. representative.

Rounding out the evening, Nevada polls close at 10 p.m. Eastern. Republicans in the Silver State will choose their fighters to take on Democratic Sen. Jacky Rosen in the state's battleground Senate election, along with three House districts that they're hoping to flip from blue to red this fall.
