Carson’s associates described a political network in tumult in interviews Friday, saying the retired neurosurgeon’s campaign chairman, national finance chairman, deputy campaign manager and general counsel have all resigned since Carson formally launched his bid last month in Detroit. They have not been replaced, campaign officials said.

The moves gutted the core of Carson’s apparatus and left the 63-year-old first-time candidate with only a handful of experienced aides at his side as he navigates the fluid, crowded and high-stakes contest for the Republican nomination…

The overlapping super PACs have confused Carson supporters about where to give money. Doug Watts, a Carson campaign spokesman, described Run Ben Run as a rogue operation: “We spend a great deal of time explaining to our supporters, ‘They’re them, we’re us.’”…

Carson occasionally drops by his Alexandria campaign headquarters, but his main interaction with staff comes just once a week, at 10 a.m. on Sundays, when he participates in a conference call to go over his schedule for the coming week.

“Dr. Carson doesn’t get involved in the minutia of things,” Williams said. “You have to understand his personality. He’s informed, but this whole process is new to him, and he’s relying on the judgment of others.”
