Sanders electorate vs. Clinton electorate

[Orser67]

I posted something similar regarding the Cruz vs. Trump electorate, so I wanted to post this for the Democratic primary.

In Identity Crisis by John Sides et. al, the authors noted pointed to some key differences between the Sanders and Clinton electorate:

-Clinton voters were far more diverse (e.g. Clinton won 77% of black voters and 51% of white voters)
-Sanders voters were far younger (Clinton won two-thirds of voters over 45, about half of voters between the ages of 30-45, and one-third of voters under 30)
-Self-identified Democrats were more likely to support Clinton, Democratic-leaning independents were more likely to support Sanders.
-Sanders voters expressed more economic anxiety and more concern about economic inequality

Some other differences:
-Clinton won 62% of women and 50% of men
-Clinton did quite poorly with the relatively small number of Democratic primary voters who expressed sexist attitudes
-Sanders did better among self-identified liberals than with self-identified moderates
-Sanders voters expressed less trust in government
-Sanders voters were a little more likely to favor raising the minimum wage and increasing government spending for child care

Some things that weren't strongly correlated with support for Sanders or Clinton:
-Racial attitudes among whites (which were a key factor in the Republican primary)
-Views on trade, taxes, or healthcare

I think the race gap is misleading because older Democrats in certain states are disproportionately black or hispanic.

I think Sides et. al would disagree with this interpretation, as they seemed to view race as the single most important factor, followed by partisan identity.

Age was the single largest difference in 2016. Even when looking at racial preferences (which on the surface perhaps seemed like the strongest divide), they more or less dissolve - at least in absolute terms - in the context of age.

I think it's reasonable to argue that age was the largest difference, but I don't think it completely overrode race. E.g. exit polls found that Sanders won about 50 percent of black voters under 30, which was a major underperformance compared to Sanders's overall share of the under-30 vote. Yougov also found that Clinton did better with non-whites over 45 than she did with whites over 45, and that she did better with non-whites under 45 than she did with whites under 45.
