26.8%. Pete ButtigiegButtigieg will claim victory, but the difference between him and Sanders is, for all practical purposes, irrelevant as a predictor of future results. Warren hasn’t fallen as far as the polls suggested, Biden did poorly as expected in nearly monochromatic Iowa.
25.2%. Bernie Sanders
18.4%. Elizabeth Warren
15.4%. Joe Biden
12.6%. Amy Klobuchar
Between them on the hard left, Sanders and Warren are getting roughly 43% of those who bothered to caucus, caucus turnout was generally less-than-robust. With that many precincts reporting, I would not expect the final percentages to differ greatly from those above.
Note: After posting this, I discover that RealClearPolitics is reporting slightly different numbers which put Sanders very slightly ahead of Buttigieg. I don’t know what to make of the discrepancy.
