If you're wondering where the data model stands as to who has the best chance of winning the nomination outright, it's Sanders, then Biden, then Warren—with Biden staring down finishing behind Warren in each of the first two contests. Klobuchar doesn't appear in the model at all. 
PS/ I mention this because I have great respect for Sanders, but there will, of course, be some Granite Staters looking for a different option tomorrow—and Biden is a particularly tough call to make right now, given that his campaign has been.... depressing... in two states now.
PS2/ The model gives Buttigieg a lower chance than Warren to win the nomination because he hasn't yet exhibited the ability to draw a diverse coalition of voters. Meanwhile, Warren performs well across a number of demographics. That's one—of many—key distinctions between the two.
