Post-identity politics?
Billionaire Trump is not supported by billionaires
(he has the middle class and working poor)
Hispanic Cruz/Rubio are not supported by Hispanics
Female Hillary is not supported by females
Jewish Bernie is not supported by Jews / Old Bernie is not supported by old people
African-American Carson is not supported by African-Americans
I'm sure that Bernie Sanders has a lot of support among Jews. I don't know what the numbers are though.
No he does not. He is a secular Jew & has moderate support
A solid majority of American Jews are secular.
But overall I love your post.
