@revelette2,
No, I'm little troubled by the Sanders phenomenon. Though there is obviously something similar apparently going on in the two cases, both the magnitude and the causes look very different, for the most part. There's nothing going on with the Dems that matches what happened to Boehner and Cantor, for one quick example (the Freedom Caucus extremists versus everyone else). There's nothing matching the Koch network with its anti-government John Birch ideology and its array of billionaire funders. There's nothing like the Norquist Pledge nor anyone like Norquist with the organization/power he has developed and wielded over GOP reps. There's no faith group comparable to the southern evangelicals and the Catholic conservatives actively enforcing an extremist theological orthodoxy through activism and via ensuring that those not on board are primaried out. Etc.
And if we look at left wing leaning media persons and outlets, we don't have anything even slightly similar to what we see every day coming from the NRO or Weekly Standard or Redstate or Fox or talk radio where real panic has set in regarding the future of the party and movement along with the evident internecine warfare, one part set against another part.
Where I think we can see something quite similar or identical on both sides is a manifestation of what has been termed "Green Lanternism" - the delusional, romantic, naive notion that One Special Person in the White House can, if bold enough, brave enough and passionate enough can overcome the existing power structures and dynamics of a country like modern America and do it over night, or in four years, or eight. Many Sanders' fans like many Trump fans perceive incrementalism as weak-kneed, corrupted betrayal. The Occupy Wall Street phenomenon was exemplary in holding that most any instance of internal organization or long-range planning must inevitably lead to corruption. But we'll note that this is pretty much limited on the left to a small portion of that base while on the right it has become very pervasive, and a key reason is this...
The modern right is now so inculcated with the ideology that government is the source of almost all the bad things that happen in the nation that they inevitably had to end up where they are now - where government cannot, axiomatically, cure the negative characteristics or tendencies that government, at any point in time, might manifest.
It is that reliance on the Strong Man (authoritarian, totalitarian) figure that has been bred into movement conservatism that scares me. Michael Gerson can't stop that now, nor can Krauthammer nor Jeb Bush. And the financial dynamics pushing this forward on the right (Glenn Beck made 80 million bucks three years ago, Limbaugh makes nearly that much every year, Fox makes billions, etc and that doesn't even begin to address the many billions being made by financial and corporate entities through inculcating hatred of citizen government. Hatred of governmental and intellectual institutions has been purposefully promoted and over a half century, that has caused levels of damage that might not be reparable. Just ask Trump's brownshirts.
