"Nikki Haley's Clash with Trump Escalates in New Hampshire"

Republican presidential candidate Nikki Haley has intensified her criticism of frontrunner Donald Trump ahead of the New Hampshire primary, targeting his mental acuity, foreign relations, and establishment ties. Previously focused on rival Ron DeSantis, Haley's shift in strategy reflects her growing pressure to secure a victory as the primary becomes a two-person race. This marks a departure from her previous avoidance of Trump-related discussions, with Haley now following Trump's lead by opting out of New Hampshire debates.
