They are the professional opinion makers plying a discussion framing trade in the media - some well intentioned and others not. They are the career politicians acclimated to playing by traditional rules on a field of conventional wisdom assumptions - some well intentioned and others not.

Now they awake to find Bernie Sanders winning a landslide of historic proportions in the nation's first primary against the no longer presumptive nominee of the Democratic Party, and they are down to essentially their last excuse. They say Bernie Sanders has tapped into a deep vein of public resentment against the status quo. They say the electorate is in an angry mood. They say that support for Bernie Sanders is a message to the establishment, a giant wake up call protest vote indicating that their needs are not sufficiently being addressed. Implicit in that assessment is a belief that someone other than Bernie Sanders, someone with, they would say, a more realistic platform, will find the right words to acknowledge the public's dissatisfaction with the status quo and then ride that to their own electoral success. They say that might still be Hillary Clinton, or perhaps Joe Biden or John Kerry in a pinch.
