Elizabeth Warren is likely to become the Democratic nominee. Warren’s success comes from several areas:

Her ability to unify upper middle class white liberals that supported the Sanders campaign. Her status as making history as the first female President. A massive amount of candidates splitting the vote Competing with Sanders as to who is the most liberal has now been a less contentious fight as most candidates have adopted most of his 2016 policies. The eventual coalescing of the anti-Biden vote. Better fundraising figures. A more organized ground game. Her status as a good debater, which will help her even more when the race narrows to two to three people.

Warren wins even if Sanders remains in the race, because the two have different bases, but in a brokered convention their delegates would join forces to ensure one of them gets the nomination. The following scenario is if Sanders remains in the race.
