Former President Donald Trump achieved a decisive 30-point win in the Iowa GOP caucuses, more than doubling his 2016 support and affirming his strong hold on the Republican Party. A Fox News poll showed that Trump led across various demographic groups, including those without a college degree, very conservative voters, and rural caucusgoers, signaling his broad appeal within the party's base. Republican voters prioritized mental fitness and strong leadership in their nominee, with a secondary focus on the ability to win in November and policy ideas.
