Former Gov. Peter Shumlin (D), who was Vermont’s governor from 2011 to 2017, told Politico that Sanders, an independent and a self-described Democratic socialist, lacks loyalty to the Democratic party.

“What I’ve seen in Bernie’s politics is he and his team feel they’re holier than the rest. In the end, they will play dirty because they think that they pass a purity test that Republicans and most Democrats don’t pass,” Shumlin told the publication.

“What you’re seeing now is, in the end, even if he considers you a friend, like [Sen.] Elizabeth Warren (D-Mass.), Bernie will come first. That’s the pattern we’ve seen over the years in Vermont, and that’s what we are seeing now nationally,” he added.
