Trump widens lead over GOP rivals in Iowa and battleground states

Former President Donald Trump expands his lead in the Republican presidential nomination race, with strong support in Iowa and critical battleground states. In Iowa, Trump's first-choice support surges to 51%, positioning him as the clear front-runner for the caucuses. Florida Governor Ron DeSantis sees a modest increase in support, while former United Nations Ambassador Nikki Haley holds steady. Trump's dominance is pronounced among key demographics, including evangelicals, Republicans, and first-time caucus-goers. Trump also holds a significant advantage over President Biden.
