An aside: Lot of ganging up against B_T, whom I like. I guess he puts himself out there for that blowback, but can't fault his resilience.
Being a Bernie supporter (now and 2016), I see Bernie being defeated as another missed opportunity for our nation to take a bold step forward. We already know what Biden (in the mold of Bill Clinton but a pale copy in every sense, including stopping at first base 🙂) is and his presidency will be the same policies of the last 3-4 decades that we think have led us to this point, from 1%ers and mega corps to wasting lives/money on wars and hollowing out middle class opportunities.
2020 Democrats have spoken and Biden is the rep, but I think those who believe Bernie would have been too radical and not get things done are being myopic. In 2008, there was a lot of enthusiasm and hope for our country getting over a dark problem of racism and inequity with the election of Obama. Of course, he didn't solve the racism problem, but, both symbolically (through educated, proud and loving first family) and rhetorically (speaking in personal terms regarding violence/opportunity for blacks), if not legislatively, he fundamentally changed the dialogue and broke the ultimate glass ceiling. I think Bernie would have done at least the same in terms of genuine care for people as people, and would have turned our national conscious away from the current approach where the people are as seen as grist to the capitalism mill, and a hunger games vibe to the have nots whereas it is who you know for the haves. And this change in atmosphere would have made a Bernie-like successor far more likely to get elected and effect long term course correction.
Now, I am afraid that only a catastrophe may bring a change, and there is a high likelihood that, given the conditions, that change may be worse than what we have known in our lifetimes.
