there seems to be confusion on who are "educated" when it comes polls.
just 1 example,
la times tracking poll
in its breakdown, "college grad or up" go for clinton >50%, while trump is in 30%s. trump wins other categories of education in that poll.
but when it comes to income, trump wins "more than $75k"(smaller margin) and "$35-75k"(bigger margin) , while clinton wins "less than $35k"(bigger margin).
but all studies say income and education is highly correlated in usa.
so how to explain this anomaly(income and education giving different preferences) in poll( which is similar in other polls that offer breakdowns like that).
a partial explanation is race. as la times says "clinton holds a distinct edge among lower-income voters, reflecting her strong support among blacks and latinos. " in fact, its blacks who go for clinton 87 to 4.
but that explains only lower income category.
