You’re right, Nathaniel, this isn’t a real primary. If nothing really dramatic happens, Trump is going to easily walk to the nomination. My silver lining: Super Tuesday marks the start of our downballot primary season, with primary races for Senate in California and Texas, and primaries for House races in five states. So perhaps we’ll have something more competitive to talk about soon.

Well, this wasn’t the most eventful primary night I’ve ever live-blogged. But this gave me a chance to reflect on the increasingly unusual nature of Haley’s candidacy. I can see an emerging narrative about her speech, in which she positioned herself directly against the polarization represented by a Biden-Trump matchup. Haley is a former member of the Trump administration, yet she’s positioned herself more and more as a Trump alternative — not a Trump substitute. She’s focused mainly on the electability issue, but she did sound a bit like a center-right third party candidate there. That’s not all that struck me though — Haley has also run an explicitly gendered campaign, talking about her 5-inch heels and “if you want something done, ask a woman.” She is only the second woman to win delegates in Republican primaries or caucuses. (Carly Fiorina was the first.) As we track the (Trump-dominated) horse race, we shouldn’t lose sight of what a unique candidate she is.

If Haley truly does drag this out through Super Tuesday, I’m curious what she expects to gain from losing in a couple dozen more states. I get that her motivations are bigger than becoming the nominee at this point, but will such a thorough thumping serve such goals? Only time will tell!

Tonight, Trump became the first non-incumbent Republican in the modern primary era to win all three of Iowa, New Hampshire and South Carolina. Haley has failed to win New Hampshire despite demographics that were practically engineered in a lab to be good for her, and she failed to win South Carolina despite it being her home state. Trump is going to be the nominee; it’s time to start treating the primary as over.

As of 9:20 p.m., 70 percent of the expected vote is reporting in South Carolina, and Trump is leading Haley by 20 points. It’s a decisive victory for the former president, as expected, though a somewhat smaller margin than his average lead in the polls heading into today (around 28 points).

Haley’s margin of defeat, though, looks even larger when it comes to delegates: Under South Carolina’s delegate allocation system, over half the state’s 50 delegates are awarded to the statewide winner, while the rest are awarded by congressional district. It looks like the maximum delegates Haley could walk away with in her home state tonight is three, if she holds onto her lead in the 1st District.

Despite this, Haley proclaimed in her speech that tonight’s result demonstrated her home state’s frustration with the country’s direction and reiterated her promise to stay in the race.

And on that note ... We hope to see you back here for our Super Tuesday live blog on March 5! We're gearing up for an eventful night tracking not only the presidential race in 15 states (and one territory) but a slew of down-ballot primaries in Senate, House and gubernatorial races as well.
