There are still 464 SDEs left to award in #IACaucus. 145.51 of those are in Polk County, and the lion's share of those are in Des Moines, where Sanders did very well. I don't think Sanders will beat Buttigieg, but I'd be a bit surprised if the gap doesn't narrow.
Another 118.31 SDE's are left to award in six other large counties where Bernie leads (Linn, Story, Black Hawk, Pottawattamie, Woodbury, and Johnson). Again, I doubt he's gain enough in these places to overturn Buttigieg's lead. But he should narrow the gap some.
Finally, there are 60.27 SDE's left in two large Mississippi River counties, Scott and Dubuque, where Buttigieg leads. The precincts left, however, tend to be in the urban areas (Davenport and inner Dubuque) where Sanders has been winning. Don't be surprised if he gains here too.
In sum, 324 of the 464 SDE's left to award are in counties Sanders is leading and/or in cities where he is doing well.
