On March 7, 1927, the United States Supreme Court decided Nixon v. Herndon. The case arose after an African American living in Texas was denied the right to vote in a Democratic primary election. A Texas statute stated– “in no event shall a negro be eligible to participate in a Democratic party primary election held in the State of Texas.” The Supreme Court found the statute unconstitutional.
Justice Holmes explained– “it seems to us hard to imagine a more direct and obvious infringement of the Fourteenth [Amendment]. That Amendment, while it applies to all, was passed, as we know, with a special intent to protect the blacks from discrimination against them.”
