Percentage of support for candidates whose mind is made up
Sanders 59%
Warren 48%
Biden 44%
Buttigieg 40%
These numbers don't surprise me at all. I thought that Sanders was underestimated in IA due to the hardness of his supporter base relative to the other candidates.

Anyway, good poll for Sanders and Warren (maybe her campaign still has some life?), but horrendous for Biden and especially Buttigieg. Getting that kind of result in IA when he's been banking on it for so long should stop his campaign dead in its tracks.
