I at least half agree.  Sanders has been and independent (iirc) for about forever and has held his basic socialist views for as long as far as I know, but in honesty, I never actually studied him or paid a lot of attention to his activities.  He has always been in a class of other independents who I had some respect for (Chaffee, Specter, to be specific.)  I don't doubt that the establishment has animosity toward him, and it would probably nearly equal that which they feel for Trump if Sanders were an actual threat.

This establishment animosity would be nearly the sole reason I would vote for Sanders at this point.  In terms of having hope that he would accomplish anything positive as president, I have none.  As an 'old timer' in his situation, I think it possible that he has an 'America First' instinct, but he also may very well be led by the nose into the (very false) promise by the globalists that they are taking us into a Utopian collectivist world.  I just don't see any signs that he is anything but a stary-eyed dreamer who will blindly follow anyone who utters the word 'peace' a few times.  Even if not, I don't sense that he has any very realistic views on how to usher in 'Socialism' (much more than we already have), and more and more think we are to far down that road already.  If we could get rid of the 'crony' aspect of the residuals of our 'Capitalism' that would be a plenty good start point, and it seems that Trump is making the most compelling case to date that he might be the one who is capable of doing this.

As for the 'Illuminati', call it what you will but there are a relatively small group of very wealthy people who are the driving forces behind the 'new world order' or 'new world economic order' that MANY politicians have mentioned.  In many/most cases the wealth come from a dynastic family (or being a functionary of one) or the banking system or often both.  Being ultra-wealthy means owning seats on the boards of multi-national corporation which translates into having a high degree of influence.  For all intents and purposes, this framework of ownership constitutes 'the establishment'.  Sorry, but that's the way it is.  Many people are waking up to it.
