Eadon, [a 36-year-old former chairman of the Iowa Democratic Party who endorsed Sanders this month, and] who was previously with Julián Castro’s campaign, didn’t take Sanders seriously in 2016. Two things changed since then. A painful nerve disease forced Eadon to become intimate with the absurdist horror of America’s health care system. And he said he saw Sanders expanding the electorate. “His ability to keep bringing in new people, and people that have not been involved before, is just such a strength electorally,” said Eadon.
This is the paradox helping to fuel Sanders’ rise: The more he attracts people who are heedless of traditional electability concerns, the more electable he looks (emphasis added).
