Former President Donald Trump secured a historic 30-point victory in the Iowa GOP caucuses, significantly increasing his support from 2016 and showcasing his enduring influence in the Republican Party. A Fox News Poll found that Trump was widely popular among various groups, including those without a college degree, very conservative voters, and rural caucusgoers.
