Your theory would have been more plausible had you pointed out the exact circumstance that Bernie is finding, near landslide wins at the polls but trailing horribly in delegate count due to superdelegates.
Adding a second challenger to Hillary would only compound the problem.
I am convinced that 99% of the Bern backers have no concept of the importance of Capital in a business.
Hence, they do not comprehend that socialism is strictly a parasite . . . one that can be tolerated without killing the host, up to a point, as in Europe, only because the U.S. defends them against the USSR and other threats.
Many ignorant people think the USSR somehow got socialism wrong . . . again, because they do not comprehend that if a system offers no incentive for investment and enterprise, the ONLY approach to making people work and building factories is CONFISCATION of PROPERTY, and ENSLAVEMENT.
