Interesting Factoid about Sanders

When you take a look at at previous "insurgent" challengers, they tended to get a lot of support from more affluent Democrats.

Not for Sanders:

Sanders’s strength with voters making less than $50,000 a year  —  and his relative lack of appeal among voters making above $100,000  —  sets him apart from Democratic primary challengers in years past like Bill Bradley, Howard Dean, and Barack Obama. All these “progressive” underdogs attracted their strongest support from wealthier voters, while struggling, in relative terms, to win lower-income support. (Nate Cohn notices the same trend in today’s New York Times.) 

Also this:

Bernie Sanders’s coalition once looked very familiar: He had strong support among well-educated and affluent liberal white voters of the sort who backed Barack Obama, Bill Bradley and Jerry Brown. He struggled among less affluent voters.

But his coalition has evolved over the last few months. He now fares much better among less affluent whites than Mr. Obama did eight years ago, suggesting he’s attracting a group that traditionally supports more moderate establishment candidates, someone like Hillary Clinton. If confirmed in the voting, it would vindicate his hope of building a progressive coalition based more on class than the coalitions put together by liberal predecessors.

I'm not surprised that the Democratic establishment hates Sanders.

There is an saying, "Republicans fear their base, and Democrats hate their base."

To the degree that Sanders talks to the base, and talks about the existential issues surrounding excessive (and undeserved) inequality in our society.

He is talking directly to the base, and they hate him.

It should make interesting time in South Carolina.
