Except the candidates will be Biden/Warren.
How does Biden get enough delegates to win the nomination? The dates for the primary ballots are all passed. If Clinton gives away her delegates, do you think the under-25 year old, rabid Bernie supporters are going to just vote for whoever the DNC chooses for them?
You think the revolution on the Republican side against the establishment is bad, image what happens on the Democrat side if they try to undercut Sanders.
1968 will look like a fistfight in the parking lot.
