Anyway to answer your question, Biden will very likely take the lion's share of the delegates pledging the day after tomorrow. That's 63 out of SC and 48 out of Nevada. The polls really don't mean much. Moderate candidates will have, combined, more than double the delegates that Sanders will have. Then, the field will narrow and some of that will be consolidated into one moderate candidate. Maybe Warren will call it and half her delegates (if even that) will go to Sanders, so maybe 3. I predict that by Wednesday, Sanders will have 50+ delegates and moderate candidates will have more than 100. After Super Tuesday, it will be just 3 or 4 candidates, maybe Sanders, Buttigieg, Biden and Bloomberg. Sanders will have less than a quarter of the candidates that the moderates have combined. By the time the race narrows to one moderate candidate against Sanders, it will be a complete slaughter and Bernie will be desperate to convince us that he still has a chance of winning the nomination despite having less than a quarter of the delegates pledged to him that the moderate candidate has, be it Buttigieg, Bloomberg or Biden.
Sanders WILL NOT be nominated by the DNC. That's my prediction. Furthermore, I predict that he will not concede his utter defeat and will continue to tear the party apart in a desperate attempt to hand Trump the presidency.
