Sanders v. Clinton endorsements

See this article for the details. The introduction:

"In the war for endorsements in the Democratic presidential primary, there is a clear trend.
Every major union or progressive organization that let its members have a vote endorsed Bernie Sanders. Meanwhile, all of Hillary Clinton’s major group endorsements come from organizations where the leaders decide. And several of those endorsements were accompanied by criticisms from members about the lack of a democratic process. It’s perhaps the clearest example yet of Clinton’s powerful appeal to the Democratic Party’s elite, even as support for Sanders explodes among the rank and file."
