"This is about the country. It’s not about you."

This is the most important passage in the article by Molly Ball linked to below:

I asked Howard Dean, Sanders’s fellow Vermonter and onetime insurgent Democratic presidential candidate, whether he approved of the way Sanders is conducting himself these days. “No,” said Dean, who has endorsed Clinton. But he said he understood.

Near the end of Dean’s 2004 campaign, he told me, just before the Wisconsin primary, he had started to realize he was going to lose, and he was bitterly angry about it—the unfairness of the process, the way he’d been treated. Late that night, the phone rang in his hotel room in Milwaukee. It was Al Gore, the former vice president, who had endorsed him.

“I ranted and raved for 10 or 15 minutes,” Dean recalled. “And when finally I stop for breath, he says, ‘This is about the country. It’s not about you.’ That stopped me in my tracks.”

Dean quit the race the next day. Accepting defeat, he said, was a process. “Having been there, it’s a gradual landing you have to bring yourself into,” he said. The question, he suggested, is whether there is someone close to Sanders who can say to him what Gore said to Dean.
