That the establishment would fight back against an insurgent populist is no surprise. Indeed, many progressives are reading this as a good thing, a sign that their candidate is authentic. Crowds at Sanders' events continue to grow and Monday in Iowa, despite an unprecedented cold shoulder from the party leadership, he beat expectations.
In a previous post, where I contrasted the views of the political "Left" with those of the "Right," I pointed out that both right and left really do claim to hold the same goal: a prosperous and relatively decent life for every human being on the planet. The only real argument seems to be on how to actually achieve it.
