Ehh, I think there was an organized effort to stop Bernie, more or less, and those endorsements were a big part of it. And it worked. Bernie& #39;s campaign didn& #39;t think it would work, even made fun of the establishment for trying. But it worked. https://twitter.com/Robillard/status/1247214315557597185">https://twitter.com/Robillard...

The questions are 1) why did such an effort take place? and 2) why did it work? And I think the Sanders campaign has a lot of thinking to do about how much of an us vs. them mentality it had, and it& #39;s lack of work in building alliances across the party.

It also shouldn& #39;t be surprising it worked. For years the evidence was on the side of the nomination being a coalition-building exercise that punishes factional candidates. Bernie gambled on Trump 16 being a new normal. They were wrong; it was the exception to the rule.
