Hillary may be starting to talk about issues, but talk is cheap and her donors are not. When you give someone a million bucks you OWN them. They will not vote against your interests, any feel good legislature she puts forth will be utterly designed to fail, and she can just blame it on the Republicans. "See friends,I tried" Bernie is the only candidate that will get grassroots support to actually force through changes. There are Independents and Republicans who will vote for Bernie, and walk away from Hillary. When Hillary says that Bernie's doing good for the party, because people are registering to vote, they are note going to vote for her. She represents everything they are voting against.

And this is some of the nastiest political backstabbing I've ever seen. Will voters keep voting for them
after something so slimy.
