"Nikki Haley's Challenge: Beating Trump in the New Hampshire Primary"

The New Hampshire primary election is underway, with Nikki Haley and Donald Trump making last-minute appeals to voters. Haley, a former United Nations ambassador and governor of South Carolina, is vying for the Republican nomination against Trump, who is facing 91 felony charges but leading in national polls. President Biden, not on the ballot, has a write-in effort in his favor. Voter turnout appears to be high, with long lines reported at some polling places. The outcome in New Hampshire could be crucial for Haley's chances in the Republican race.
