Partial Iowa caucus results

Partial Iowa caucus results released with 62% of precincts reporting:

Pete Buttigieg: 26.9%
Bernie Sanders: 25.1%
Elizabeth Warren: 18.3%
Joe Biden: 15.6%

538 had some more stats. What's up with that "state delegate equivalent distribution?"

"With 62 percent reporting, the first alignment vote is Sanders 24 percent, Buttigieg 21 percent, Warren 19 percent, Biden 15 percent and Klobuchar 13 percent. The post-alignment vote is Sanders 26 percent, Buttigieg 25 percent, Warren 21 percent, Biden 13 percent, Klobuchar 12 percent. The state delegate equivalent distribution is Buttigieg 27 percent, Sanders 25 percent, Warren 18 percent, Biden 16 percent, Klobuchar 13 percent. Again, this is with only about three-fifths of the vote reporting. In effect, we’ve dropped into where we would have been around 10 p.m. on a normal caucus night. We will update as more of the vote trickles in!" 5:09 pm EST
