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.

Polls are open in the Palmetto State, the latest battleground in the GOP presidential primary race. You'd be justified in asking if this will also be the contest's last battleground, as Trump's commanding lead in the polls suggests he'll almost certainly walk away with all the delegates tonight and continue his march to the nomination. We'll certainly be looking out for Haley to signal what she'll do next: She's insisted that she plans to stay in the race, but a big home-state loss could throw cold water on an already-struggling campaign.

As for the timing of it all, polls will close at 7 p.m. Eastern, and we wouldn't be surprised if a winner is projected not long after. As usual, though, we plan to stick around to analyze results and candidate speeches throughout the evening. We'll also discuss how Trump got to be the overwhelming favorite on Haley's home turf, whether there are any upsides for Haley as the last challenger standing and (gulp) what it all means as we turn toward November's general election.
