"Chris Christie and Nikki Haley Face Dean Phillips Challenge in New Hampshire"

Dean Phillips' entry into the Democratic primary in New Hampshire is posing a challenge for Republican candidates Nikki Haley and Chris Christie. Both Haley and Christie have been polling well among independent voters, who make up a significant portion of the electorate in the state's open primary. However, Phillips' campaign is already drawing support from independents, potentially diverting votes away from the Republican candidates. The impact of the Democratic primary on Haley and Christie's campaigns remains uncertain, but any shift in the electorate could alter their trajectory in the race.
