Sinclair suggested that the fact that Harding received two-fifths of the Southern vote in 1920 led him to see political opportunity for his party in the Solid South. On October 26, 1921, Harding gave a speech in Birmingham, Alabama, to a segregated audience of 20,000 Whites and 10,000 Blacks. Harding, while stating that the social and racial differences between Whites and Blacks could not be bridged, urged equal political rights for the latter. Many African-Americans at that time voted Republican, especially in the Democratic South, and Harding stated he did not mind seeing that support end if the result was a strong two-party system in the South. He was willing to see literacy tests for voting continue, if applied fairly to White and Black voters.[164] "Whether you like it or not," Harding told his segregated audience, "unless our democracy is a lie, you must stand for that equality."[8] The White section of the audience listened in silence, while the Black section cheered.[165] Three days after the Tulsa race massacre of 1921, Harding spoke at the all-Black Lincoln University in Pennsylvania.
