It's now Bernie's race to lose

Unlike in Iowa and New Hampshire, there aren’t really any qualifications or caveats about Sanders’s victory here. Nevada is a diverse state, and Sanders did well among a broad array of demographic groups, including winning 53 percent of Hispanics and 27 percent of African Americans, according to the entrance poll. This is a pretty good electorate for Sanders: young, working-class, unionized, heavily Hispanic. But he’s also worked hard to cultivate support from those groups of voters — Hispanic voters weren’t a major strength of his in 2016 for example. Perhaps fortunately for him, there are also plenty of these types of voters in the two biggest delegate prizes on Super Tuesday, California and Texas.

In addition to being the most likely winner overall, Sanders is by far the most likely Democrat to win the nomination with a majority of pledged delegates. Other candidates are mostly hoping for a messy outcome in which they win the nomination by plurality — potentially at a contested convention.

We don’t have enough results as of this writing to officially update our forecast model, but the first two of these prebaked scenarios we built should give you a rough idea of what it will say…
