It seems like ancient history — eight years ago — but in 2016, with Ted Cruz winning first place and Marco Rubio coming in a close third after Trump, there was a brief moment when it looked like the party was trying to coalesce to some extent around Rubio as the non-Trump (and non-Cruz) alternative. This effort didn’t get very far, but I wonder if the same dynamic will come into play here, with most of the Republicans who have reservations about Trump coordinating around one of the other contenders.

I absolutely think Haley or DeSantis can still put together a winning narrative about tonight, based on whichever candidate finishes second. We all expected Trump to win, so there is nothing surprising about it. That will produce ho-hum headlines, whereas the fight for second could be more exciting. Haley could take a second-place finish and go to New Hampshire with positive coverage about that result — and besting DeSantis. Meanwhile, DeSantis could play up a "comeback kid" narrative if he grabs second after Haley seemingly had been the candidate on the upswing. This doesn't mean either has much of a chance of beating Trump for the Republican nomination, but either narrative could extend the race a bit, depending on how voters in the subsequent contests react.

Tia, I think the most likely case of either Haley or DeSantis coming out of tonight with momentum is if DeSantis stays ahead of Haley and he can spin a “comeback kid” narrative out of that. We know that the media (and voters!) love a comeback narrative, but the DeSantis campaign has just been one negative development after another for the past few months, so it’s been hard for him to get that narrative going. But look, we know that in certain corners of the GOP there’s a lot of money and interest in having a credible non-Trump candidate. Right now everyone seems to think that’s Haley, but if DeSantis can reclaim that mantle, he could be able to stick it out to Super Tuesday or beyond.

I actually do think there's room for a non-Trump candidate still. Either Haley or DeSantis could try to craft a winning narrative out of a second-place showing. More than that, though, there's some appetite in the party for someone who isn't Trump. Combine that with the uncertainty of what will happen to Trump given the criminal cases against him, I think anything could happen. More than that, I think the 2016 election showed me that anything is possible, even the unexpected, so I'm trying to keep an open mind.

Trump gave a victory speech to supporters in Iowa at about 10:30 p.m., and spent an uncharacteristically long time talking about other people. He thanked his supporters, his family, and even his opponents. It took several minutes for him to pivot to his target for the night: Biden, and, in doing so, he picked up the mantle of presumptive nominee.

Here, he listed some of the themes of his campaign, immigration and increasing energy production. He borrowed a phrase from former vice presidential candidate and Alaska Gov. Sarah Palin and said, "Drill, baby, drill." (He even made a joke about electric vehicles.) In talking about immigration he repeated a number of falsehoods about a border that's out of control and immigrants coming in from "insane asylums," echoing some of the themes from his 2016 campaign launch.

In truth, Biden has ramped up deportations, deporting more families and children than Trump did in his last year in office. But border crossings have surged regardless, Republican voters care a lot about immigration, and voters trust Republicans more on the issue. In a reversal of 2020, Trump is poised to be a challenger instead of an incumbent president in this round, and he's already throwing punches.
