Uncertainty looms over Iowa GOP debate as potential candidates remain noncommittal

Former South Carolina Gov. Nikki Haley has not committed to appearing at the final GOP presidential primary debate hosted by CNN in Iowa, while only Florida Gov. Ron DeSantis has confirmed his participation. Former New Jersey Gov. Chris Christie and entrepreneur Vivek Ramaswamy are unlikely to qualify. CNN requires candidates to show three national or Iowa polls with the candidate at 10% or higher, posing a challenge for Christie and Ramaswamy. Haley continues to push for Trump's attendance at a GOP debate in Iowa.
