After some editing:
Bernie Sanders believes:
A. The most likely path for a much-needed progressive shift in the USA is via a successful presidential run by someone (him) running for a duopoly nomination as a Democrat;
B. A mass grassroots electoral mobilization around anti-oligarchic economic issues has real potential to shift power away from capital without mass violence (a “political revolution” by which Sanders really means an electoral revolution because all revolutions are political, just sayin’);
C. Effective mobilization around anti-oligarchic economic issues is a necessary step toward racial and social justice in the USA;
D. The neoliberal neocon Democratic Party power establishment will, without hesitation and without question, seek to undermine and marginalize him at every moment, but;
E. A grassroots mobilization has a real chance to overcome Party machinations and secure him the nomination; and:
F. He is by far the best candidate to go toe-to-toe with Trump and whip his ass.
He could be wrong, but he’s sincere. It’s a long-shot, but he has a chance. His main hurdle is the Democratic Party establishment. If he gets past that, he’ll wipe the floor with Trump.
