@Blickers,
Well in the first place I think the probability of a Bernie Sanders victory in the Presidential election is vanishingly small and the probablity of that combined with a Congress that would go along with his absurd plans even smaller.
Beyond that I note that everything we know about GHW Bush's behavior before he became president and the political & economic philosophies the artiuculated and supported in those days, indicated a man dedicated to the preservation of American democracy and the traditions of free enterprise and individuasl freedom that has long gone with it. Moreover he always showed, perhaps to a fault, a willingness to work with the other side politically - and that I think was illustrated in your story. In stark contrast Bernie Sanders has been the odd man out throughout his political career, and has set himself apart from nearly everyone around him. Also in stark contrast, his experience so far in life is far narrower than that of GHW Bush when he became president.
I don't think that either CORE or ther SNCC were, in their time, either moderate or particularly democratic. Indeed they were basically radfical movements whose time came and went, and which passed from our political scene leaving little of benefit to mark their existences.
In short, while I find Sanders to be a somewhat likelable individual, I note a streak of radical authoritarinism in him that I find to be truly potentially dangerous. The good news here is that apart from his very enthusiastic (and naive) supporters, enough people in the country see those qualities and dangers so as to render him virtually unelectable as President. Indeed had it not been for the steadily growing public impression of Clinton sleeze and lies his campaign prospects would be maginal at best. Sanders popularity among a dedicated minority of Democrats is more a reflection of growing disenchantment with Clinton than acclaim for his special virtues. In this area I suspect his position is somewhat like that of Donald Trump among Republicans.
None of this is likely a surprise to you. However, it is clear that you are more interested in making a point, with a very weak case, than in critically examining the situatiuon.
