I wouldn't rule out an outcome along these lines in SC. Based on demographics and absentee voting that has been ongoing, it should be one of the very worst states for Bernie. On the other hand the question is if it really matters if Bernie is up by 15-20 or whatever in CA and doing fine elsewhere outside the deep south.
Biden could close the gap in CA if he wins SC by this much and starts to look viable in the eyes of those who want an alternative to Sanders.
Make no mistake, he won't win CA, but I don't think Sanders wins ALL of their delegates.
Mmm, doubt whatever happens in SC matters here in CA. Especially when so much of the vote will be mailed out by then. It might tip the scales in states like NC though.
