Sanders’ campaign briefly distributed talking points for supporters to use door-to-door, saying that Warren supporters “are highly-educated, more affluent people who are going to show up and vote Democratic no matter what” and that “she’s bringing no new bases into the Democratic Party.”

And the day after Warren clashed with Sanders following a Democratic debate in Des Moines, #Warrenisasnake was among the hashtags trending on Twitter.

Shumlin accused Sanders of trying to “Hillarize” Warren, saying the senator had cast Hillary Clinton, too, as an elitist, contributing to divisions in the Democratic electorate.

…”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,” said Shumlin. [and Sander is not seen to be reigning them in.]

…[Shumlin is] accusing the senator [or at least his team] of trying to “Hillarize” Elizabeth Warren.

…[Shumlin also] warned that Sanders, an independent and a self-described democratic socialist, ultimately did not feel loyalty to Democrats.

..In 2016, Sanders drew criticism for initially not campaigning for the Democratic nominee in the general election race in Vermont. He did later cut an ad …[and] stumped for Democratic candidates across nine battleground states.
