Just five weeks before the first GOP presidential nominating contest, Trump earns 51% first-choice support from likely Iowa caucusgoers, according to the latest NBC News/Des Moines Register/Mediacom poll.

Florida Gov. Ron DeSantis receives 19% first-choice support, followed by former U.N. Ambassador Nikki Haley (16%), entrepreneur Vivek Ramaswamy (5%), and former New Jersey Gov. Chris Christie (4%) in a poll that has a plus-minus 4.4 percentage point margin of error.

Trump’s 32-point lead has grown 5 points since October.
