Former President Donald Trump scored a record-setting win in the Iowa caucuses on Monday with his rivals languishing far behind, a victory that affirmed his grip on the 2024 Republican presidential nomination.In what was the lowest-turnout caucus in a quarter-century, participants endured life-threatening cold and dangerous driving conditions to meet in hundreds of schools, churches and community centers across the state.But those who ventured out delivered a roughly 30-point win for Trump that smashed the record for a contested Iowa Republican caucus with a margin of victory exceeding Bob Dole's nearly 13-percentage-point victory in 1988.Florida Gov. Ron DeSantis finished a distant second, just ahead of former U.N. Ambassador Nikki Haley.The results left Trump with a tighter grip on the GOP nomination, though it could take several more months for anyone to formally become the party’s standard bearer.The magnitude of Trump’s victory, however, posed significant questions for both DeSantis and Haley. Neither candidate appeared poised to exit the race, though they leave Iowa struggling to claim making much progress in trying to become Trump’s strongest challenger.
