“We are a group that really uniquely knows that electability is self-determining and that oftentimes it’s the people with the boldest vision and the most unlikely candidacies early on who can really shift the field,” El-Amine said. “Sen. Warren really has the zest and the grit and the gumption and the audacity that we loved that President Obama really embodied.”

Asked about the decision to support Warren over Obama’s vice president, Joe Biden, Carson declined to comment on any of the other candidates. He pointed out that Warren herself is an Obama alum, having spearheaded the creation of the Consumer Financial Protection Bureau in the aftermath of the 2008 financial crisis — something Warren frequently reminds voters of on the campaign trail.
