that says a whole lot right there..
Just because someone has "..deeply held convictions.." Doesn't mean they're the best. I don't see "stubbornness and independence" as "strengths".. necessarily. A candidate needs Coalitions and Friends to build a strong campaign. And "stubbornness" speaks for itself.
In a memo he drafted, Longabaugh recommended that Sanders demonstrate a commitment to that goal early on by kicking off his campaign with a high-profile speech on racial justice in Chicago. (He would end up delivering a kickoff speech there, but it did not focus exclusively on race.) He also suggested that Sanders court the leaders of major labor unions ― officials who had shunned him the first time, despite the depth of support for Sanders among their members.
Longabaugh left the BS campaign in 2019 over creative differences.
WTG Nina.. I'm sure you helped a lot.. not.
Turner also sometimes initiated assaults on Sanders rivals that the candidate himself had not yet engaged in. Ahead of the November debate in Atlanta, for example, Turner took thinly veiled shots at former South Bend, Indiana, Mayor Pete Buttigieg, before clarifying that she did not speak for the campaign.
More on Turner towards the end of the long long article which I totally recommend reading!
Sanders tapped Turner, a Cleveland native and his closest Black confidante, to serve as his political emissary in the state. She began courting endorsements for Sanders early in 2019, helping him line up support from nine state lawmakers ― all of them Black. Sanders himself would go on to hold 70 events in the state over the course of his run.
Turner, for example, rather than a local lawmaker, authored the January op-ed in a state newspaper blasting Bidens record on civil rights matters.
South Carolina wasn't buying what Nina was selling.
Mahalo, Goth.. Well Worth Reading!

Even though it encompassed so much I think some important things were not included, that we saw from being right here on DU.
