"Super Tuesday" on March 5 sees 15 states hosting Republican presidential nominating contests, a pivotal day with 854 delegates up for grabs.
The focus is not on states won, but on whether Donald Trump secures a clean sweep.
With a strong lead, Trump is poised to clinch the nomination soon.
The question is if former U.N.
Ambassador Nikki Haley can keep it close or will she get blown out?
