"Nikki Haley and Donald Trump Clash in Heated GOP Primary Battle"

Nikki Haley, a Republican presidential candidate, is intensifying her criticism of Donald Trump as she gains traction in New Hampshire polls ahead of the state's primary. Despite previously working in Trump's administration and having a history of both opposing and supporting him, Haley is now directly addressing Trump's attacks and those from his allies, including a pro-Trump super PAC ad accusing her of flip-flopping on a gas tax. Haley is attempting to appeal to undecided moderate Republicans and independents, while also distinguishing herself from other candidates like Chris Christie by not being as harsh in her criticisms of Trump. However, some voters remain skeptical of her commitment to opposing Trump, given her statements about pardoning him and not ruling out a VP position under him.
