I wrote earlier that pre-caucus polling showed that Iowa Republicans didn't care about Trump's legal problems. ABC's Iowa entrance polls support that. Sixty-three percent of caucusgoers said Trump would be fit for office even if he were convicted. Seventy-one percent of that group voted for him. So to Julia's earlier question, I think part of the issue, as she noted, is that while there are some anti-Trump Republicans who want an alternative, a majority of Republicans left in the party don't think Trump did anything wrong, or that even if he did, he's not disqualified from future office.

Nathaniel, Binkley spent good money for his 1 percent! Just over $3 million, according to AdImpact. I’m not sure what the cost per vote record is in Iowa, but I think he’s probably a contender. Maybe if he had spent $300 million he would have won in a landslide …

After Trump, DeSantis, Haley and Ramaswamy, the current fifth-place candidate in Iowa is not Asa Hutchinson, the former governor of the great state of Arkansas, but businessman and pastor Ryan Binkley, whom we at 538 don’t consider a major candidate. I actually interviewed Binkley last year as part of a video on what keeps long- or no-shot presidential candidates going.

Earlier tonight, Ramaswamy dropped out of the race following his fourth place Iowa finish and endorsed Trump. We've already noted how Ramaswamy was all-in in Iowa, traveling through the entire state twice. Ramaswamy had a brief moment in the sun earlier in the race, but that investment didn't really pay off. He urged his supporters to support Trump, but polls show he's already their number two choice. That could make a difference in New Hampshire, where Haley has been closing in on Trump's lead.
