We now have 34 percent of the expected vote reporting in Iowa, and DeSantis leads Haley 20 percent to 19 percent for second place. Trump, of course, is way out in front with 52 percent.

Interesting, Elliott! It seems like Trump’s focus on what happened in 2020 is not turning off Iowa voters. However, pre-election polling suggests it may not have been top of mind for most Iowa voters who were considering Trump in the caucuses. Only 40 percent of likely GOP caucusgoers who said they were considering caucusing for Trump said that payback for 2020 was among the reasons, which was the smallest share among the possible reasons listed in a December YouGov/CBS News survey. The reason chosen by the most voters, of the options presented, was that they think things were better under Trump, which 99 percent said was one of their reasons.

I agree that Trump's big win is the headline. I thought it would be closer and that a call would take longer. But if Haley can come in second, and then does well in New Hampshire, that could elevate her in a way that matters electorally, and narratively.

I think a second place for Haley would effectively kill the DeSantis campaign. That's news! DeSantis pinned a lot of his hopes on doing well in the state. But more importantly, I agree with Nathaniel: Trump's big win is the headline. CNN reported last week that the White House is frustrated that many voters do not seem to acknowledge that the general election is so likely to be Trump vs. Biden. Given that, covering Iowa for what it is (effectively the last indicator we needed that Trump is overwhelmingly likely to be the nominee) could correct some of those misperceptions.

Other than his one-vote loss in Johnson County, it's hard to find much that went wrong for Trump tonight. He won a majority of the vote and carried pretty much every demographic category (especially ones that make up the bedrock of the GOP primary electorate). The most Trump-like candidate in the race, who was still siphoning off a chunk of MAGA votes, dropped out and endorsed him. His two main challengers effectively tied, denying either of them the momentum or comeback narrative they desperately sought in Iowa. And you have to imagine the deep-pocketed donors who flooded Iowa with tens of millions of dollars of pro-Haley and pro-DeSantis advertising have to be wondering about their return on investment.

The New Hampshire primary is in eight days and might well be the toughest contest for Trump of the entire primary process, so it's good for him he can approach it with a full head of steam. The window of opportunity for any non-Trump candidate to alter the course of this race, such that it was ever open, is rapidly closing.
