Sanders could very well end up being the favorite to win the Democratic nomination, if he wins New Hampshire and Nevada and if Buttigieg/Biden/Bloomberg split up the vote in the party’s moderate lane beginning on Super Tuesday.
Sanders got 8% support from Iowa caucus-goers 45 and older. Among seniors 65-plus, it was just 4%. While he over-performed among “very liberal” Iowa Dems (43%), he under-performed among “somewhat liberals” (19%) and moderates (12%).
He got just 12% support from white women college graduates — arguably the heart of the Dem resistance against Trump. Most concerning of all for Sanders, he won more than half of the Iowa caucus-goers who said they supported him in 2016. But he barely registered (7%) among the 54% of all Iowa caucus-goers who said they backed Hillary Clinton 4 years ago.
