"Key highlights from the Republican debate: Trump's attacks, Ramaswamy's 'candor' and more"

The fourth Republican debate will feature four candidates: Ron DeSantis, Nikki Haley, Vivek Ramaswamy, and Chris Christie, with Donald Trump opting to skip the event. With Trump absent, the battle for second place between DeSantis and Haley is expected to intensify as they aim to position themselves as the clear alternative to Trump. This debate may be the final one before the Iowa caucuses, raising the stakes for the candidates. Ramaswamy plans to bring his pugnacious style to the stage, while the moderators, including Megyn Kelly, present a wild card element to the event.
