Andrew Johnson actually said...

"The board of registration have no authority to administer any other oath to the person applying for registration than this prescribed oath."

"The applicant for registration must be a citizen of the State and of the United States, and must be a resident of a county or parish included in the election district."

"No one who has been disfranchised for participation in any rebellion against the United States or for felony committed against the laws of any State or of the United States can take this oath."

"Disloyal sentiments, opinions, or sympathies would not disqualify, but where a person has by speech or by writing incited others to engage in rebellion he must come under the disqualification."
