"House Democrat Dean Phillips challenges Biden in Democratic presidential race"

Minnesota Rep. Dean Phillips has launched a long-shot Democratic primary challenge against President Joe Biden, citing concerns about Biden's age and low approval ratings. Phillips, who recently left his House Democratic leadership position, is expected to formally announce his campaign in New Hampshire's Democratic primary. His campaign strategy is causing headaches for the party, as Democrats seek to unify around Biden and lay out the administration's accomplishments. Phillips' focus on New Hampshire could hurt him in South Carolina's primary, and he may struggle to find major Democratic donors who aren't already backing Biden.
