Yes.

Seriously, though, are we really ready to call this a Sanders versus Biden race? (Genuine question.)

And unlike the conventional wisdom, the FiveThirtyEight model always thought Biden was a more viable alternative to Sanders than, say, Buttigieg or Klobuchar, even after his losses in Iowa and New Hampshire. Having a relatively broad coalition helps, and Biden and Sanders have the two broadest coalitions in the party.
