A possible loss in California has the Clinton machine in panic mode.
Bernie's victory, should he attain it, almost certainly won't propel him to the nomination. It might cause the death of the Clinton machine, however, as it is not clear that it could maintain its monetary racket without plausible access to the political influence it is selling. The scale of Clinton corruption is such that its death would be a major step forward in correcting American political corruption.
What comes next? Joe Biden, maybe. Maybe a free-for-all at the convention. Whatever it is, it would be better.
