In the fourth Republican debate, candidates focused on emerging as the top alternative to Trump for the 2024 presidential nomination.
The smaller field allowed for clearer policy discussions and personal attacks.
Nikki Haley was a primary target, reflecting her rising prominence.
Ron DeSantis and Vivek Ramaswamy criticized her connections with Democratic donors and her Boeing board tenure.
Chris Christie reminded the contenders of Trump's lead in polls and critiqued their avoidance of confronting him directly.
Christie also aimed to portray his rivals as inexperienced, particularly challenging DeSantis on critical issues.
