Blacks and the Right to Vote

Via Prof. Rapaport at Right Coast, I find that Missouri Senator Henderson said during the 14th Amendment debates:

It is only where political power is in the hands of a favored few that oppression can be practiced. It is only where oppression exists that the agents of a superior power are needed for protection. Give the negro the ballot and he will take care of himself because his interest requires it. Give him a bureau agent and he will sometimes be plundered, because his interest and the interest of the agent may differ.
