Our friends over at The 19th have pointed out that Haley is likely to become the first woman to win more than one delegate in the Republican primary. If she pulls off an upset in New Hampshire later this month, she'll become the first woman to win a Republican primary contest. In that same state, then-former Sen. Hillary Clinton was the first woman to ever win a major party primary contest in 2008, when she captured a surprise victory after coming in third in Iowa, which Obama won.

DeSantis just finished his caucus-night speech, and it sounded a lot like a victory speech. He told a raucous crowd that, despite everyone underestimating their campaign, they punched their ticket out of Iowa. Of course, DeSantis did not win the state, and his 30-point deficit to Trump raises serious questions about the future viability of his campaign. There was a lot of positive spin up on that stage.

I admit that I did not expect to hear a Gettysburg Address quote tonight, but DeSantis said it twice, and mentioned Lincoln and Gettysburg — and Reagan and the Cold War — outright.

Ramaswamy wasn't polling that well in New Hampshire — around 5 percent — but his supporters are a Trumpy group, which means a substantial number of them will move to the former president. Based on limited sample sizes, around one-third to half of Ramaswamy's voters in national and New Hampshire polls named Trump as their leading second choice. With Trump polling at 43 percent in our New Hampshire average, this might move him up a couple notches, and make it just a little harder than it already was for Haley to catch him (she's at 30 percent). Now, Haley could gain support in the next wave of polls because most surveys in New Hampshire haven't accounted for Christie's departure yet, and we know Haley is the top second choice for Christie voters. But she's set to finish third in Iowa and perhaps not get quite the glut of positive headlines a second-place showing might've produced. Overall, beating Trump was already a difficult challenge, so Ramaswamy boosting him a little more stands to make it even harder.

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.
