9:20pm: 100% is now reporting in SC-03. Duncan's sporting a 3% or 2,100 vote lead over Cash, but still no call from the AP after a short delay, the AP has called it for Duncan.
9:00pm: Given that the Ark of the Covenant is in Arizona, Tim D'Annunzio can try his next congressional run there. AP calls NC-08 for Johnson.
8:57pm: Duncan continues to hold his lead over Cash in SC-03; this territory went for Cash narrowly by 0.4% in the first round. This is a swing of 3.7% to Duncan, who needs a swing of 2.3% to win. In NC-08, Johnson continues to whomp D'Annunzio 62-38.
8:47pm: AP calls SC-01 for Tim Scott. He will likely become the first black Republican in Congress since JC Watts left office in 2003.
8:40pm: It's over for Rep. Bob Inglis - the AP calls it. Trey Gowdy has beaten him soundly. Inglis is the third House incumbent and fifth member of Congress to lose a primary/convention so far this cycle.
8:37pm: Man, maybe SSP HQ needs to take a ganja break this time! The two biggest races have been called (NC-Sen and SC-Gov), and NC-08, SC-01, and SC-04 all look like blowouts. And SC-03 isn't exactly a barnburner. We may not have much real action until Utah starts coming in later tonight.
8:33pm: Really bad news for fans of Raiders of the Lost Ark: Tim D'Annunzio is getting smashed by Harold Johnson, 68-32, with about 18% reporting. This represents an almost 15% swing to Johnson, which means Timmy D might wind up with a smaller share than in the first round. Pretty pathetic, but if anyone could pull this off, he could.
8:31pm: The one real barnburner tonight might be SC-03, the seat being vacated by gubernatorial loser Gresh Barrett. Duncan leads Cash 52-48 with over half the vote in. This represents a nice swing toward Duncan from round one, though, so it might not wind up being this close in the end.
8:30pm: Yeah, it's officially official - We Are Marshall. She'll take on Richard Burr this fall.
8:29pm: Buncha people on Twitter are saying the AP has called NC-Sen for Elaine Marshall. Really gotta wonder what the DSCC was thinking here. Time for them to embrace her fully.
8:22pm: AP calls SC-Gov for Nikki Haley. She'll face Dem state Sen. Vincent Sheheen in the fall. Unlike in SC-Sen, we definitely got the candidate we wanted in our primary.
8:19pm: Meanwhile, in SC-01, Tim Scott is cruising with a 73-27 lead with a quarter of the voted reporting. Hard to see him losing this one. I guess Paul Thurmond can go commiserate with Ethan Hastert.
8:17pm: With about 30% of the vote in, Nikki Haley is crushing Gresham Barrett 64-36. Gotta wonder what folks like Andre Bauer and the local Chamber of Commerce were thinking.
8:16pm: Terrible sign for Inglis - he's down 60-40 in his purported "base" of Greenville. He was a dead man walking for the last couple of weeks. Tonight is just the grand finale.
8:11pm: 1% of the vote has trickled in in NC-08, and Harold Johnson leads Tim D'Annunzio 70-30. This represents a 13% swing to Johnson from the first round (based on the two-candidate share of the vote).
8:04pm: True to the Greenville v. Spartanburg divide in SC-04, the one precinct from Greenville in has closed this to 70-30 Gowdy.
8:02pm: Cash has retaken the lead in SC-03 over Duncan narrowly at 50.3-46.7, but this is territory that went for him 26-19 in the first round.
7:59pm: In NC-Sen, Elaine Marshall continues to sport her 64-36 lead over Cal Cunningham. This is territory that went for Marshall 39-30 in the first round. In SC-Gov, Haley's lead is 62-38 over Barrett; this territory went for her 49-23 in the first round.
7:55pm: In SC-01, Scott's lead remains an impressive 70-30 over Thrumond. Further west in SC-03, Duncan now has a 52-48 lead over Cash.
7:49pm: Marshall's lead has ticked up slightly to 64-36 with 6% reporting in NC. Johnson is whomping D'Annunzio 75-25 with two precincts in.
7:47pm: Duncan's now taken the lead in SC-03, a slim 89-vote lead over Cash.
7:42pm: 1% reporting in North Carolina now, Marshall is up on Cunningham 63-37.
7:30pm: We only have five precincts reporting in South Carolina, and Nikki Haley leads Gresham Barrett by 61-39. In SC-01, Tim Scott leads Paul Thurmond by 67-33, and ice cream truck driver businessman Richard Cash leads state Rep. Jeff Duncan by 54-46 with one precinct counted in SC-03. Trey Gowdy is also crushing Bob Inglis by 85-15 in the early vote.
Polls have now closed in South Carolina. (North Carolina will close at 7:30pm ET.) We'll be using this thread to follow the returns.
