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.

Haley addressed supporters at about 8:30 p.m. Eastern, and vowed to stay in the race: "I said earlier this week that no matter what happens in South Carolina I would continue to run for president, and I’m a woman of my word," she said. Haley said she was frustrated and worried about the future of the country and the world, and that she was running to save it. "America will come apart if we make the wrong choices," she said. Again, Haley presented her case as one of electability. She said that we couldn't live with four more years of Biden's failures or Trump's lack of focus, and that the voters in future primaries deserved a choice, not a "Soviet-style election" with one candidate. With about 40 percent of the vote (as of now), she noted that it was roughly the same amount she'd gotten in New Hampshire. "I’m an accountant. I know 40 percent is not 50 percent," she said. "But I also know 40 percent is not some tiny group." Those people were looking for an alternative, and she said she shared their frustration. The electability argument is one that Republican primary voters aren't buying.
