Minnesota Representative Dean Phillips is expected to launch a long-shot Democratic primary challenge against President Joe Biden in New Hampshire. This decision has upset several major non-white members of the party who see it as a disregard for the emphasis Democrats have placed on diverse voters in the South. Some argue that starting a campaign by filing in New Hampshire, a state with a predominantly white population, is a sign that Phillips doesn't value diversity. Phillips' team did not respond to a request for comment.

Phillips has hinted at a bid against Biden in the past, stating that the country would be well served by a new generation of dynamic Democrats. Although he has not officially confirmed his run, his recent activities, such as a campaign bus heading to New Hampshire and a campaign van in the state, suggest that he is serious about a primary challenge.

The move to launch a campaign in New Hampshire highlights the ongoing dispute within the Democratic Party over which states should have the first say in determining presidential nominees. While Biden's name will not appear on the New Hampshire primary ballot, some state Democratic leaders have organized a write-in effort on his behalf. However, it remains to be seen how write-in votes will be counted.

Overall, Phillips' potential challenge to Biden has generated confusion and derision from his colleagues and constituents alike.
