Trump's dominance and GOP rifts on display at Iowa event.

Despite facing legal issues and questions about his perpetuation of election lies, former President Donald Trump remains the frontrunner in almost every poll of the Republican field for the 2024 presidential election. His GOP rivals are reluctant to take him on, with some fearing alienating his core supporters or taking a social media drubbing. Trump's lesser-known rivals need to use the coming months to introduce themselves to voters and make favorable first impressions before they risk alienating Republican voters by taking on the still-popular former president.
