Yes, please a brokered convention where the Super Delegates steal the nomination from Bernie and give it to Nancy. Oh the internal Democratic Party civil war would be so spectacular to watch.
The accepted assumption is that the Dems are determined to win the WH. If we consider that their real goal is the Senate (where their odds may be better), then it makes all the sense in the world for them to keep a bona fide crazy off the ticket, even as they alienate their own voters.
