The fourth Republican presidential debate in Tuscaloosa, Alabama saw the four remaining candidates battle for voters' attention. Former New Jersey Governor Chris Christie was particularly critical of fellow candidate Ramaswamy, calling him an 'obnoxious blowhard'. Former South Carolina Governor Nikki Haley was also targeted, with Christie accusing her of being too inexperienced to be president. The debate showed that little has changed since the first meeting of the candidates in August.
