The Democratic Party's Black Wing in Alabama endorsed Hillary for President. One of its member, a County Commissioner named Albert Turner, said they needed too over Barack Obama as "she's white" and thus more electable. Identity politics do lead to problems.
In the State elections last year one of the Districts in Birmingham split as the Democrats nominated a white lesbian for the role, and the black leaders in the area wanted a black person nominated. It led to law suits and argument. The white lesbian remained on the ballot and won.
