I really wish that the fivethirtyeight would break down "no one" more than they do. It's really easy for me to look at it as Sanders getting a plurality but not a majority, but some of that percentage has to also account for Biden getting a plurality. I don't think the DNC would nominate someone without the plurality. I'm guessing it's about 70% Sanders gets the nomination at this point unless the DNC actually goes with someone else in a brokered convention.
