BERNIE VS. DEM ESTABLISHMENT: In a fundraising email, @BernieSanders rallies his base behind his feud with @AmProg, calling the CLINTON-linked think tank "the epitome of the political establishment" that is "working to defeat our progressive agenda," including Medicare for All. 
NEW: @TomSteyer, a multi-million $ donor to @AmProg, is not pleased about @thinkprogress' video critiquing @BernieSanders: "I will use my voice on CAP's Board of Directors to discourage any such attacks on any candidate seeking the Democratic nomination in the future.”
WHY THIS IS SIGNIFICANT: Even in a Dem primary where candidates are distancing themselves from Big $, major donors still help set the tone, & @TomSteyer is one of the biggest. His call for more comity will get the attention of CAP, organizations like it & probably some campaigns.
