Johnson's racism is what led him to oppose, and oppose bitterly, the egalitarian aims and policies of the Radical Republicans, from land for the Freedmen to votes for them.
He was terrified of "Negro supremacy."
Would in fact the Radical program of Negro enfranchisement and rebel disenfranchisement have resulted in some states in Negro majorities among voters?
An interesting experiment, that.
