"The hallmarks of Lincoln's greatness were his ability to grow and his willingness to change his mind. During the war, he had come to embrace the Radical position on immediate emancipation and the enlistment of black soldiers, both policies he had initially opposed. In 1864 he privately suggested to Governor Hahn that Louisiana allow some blacks to vote under its new constitution, singling out the educated, propertied free blacks of New Orleans and those who had served in the Union army. In April 1865, shortly before his death, Lincoln for the first time publicly stated his support for this kind of limited black suffrage... Andrew Johnson lacked Lincoln's qualities of greatness. While Lincoln had been open-minded, willing to listen to criticism, attuned to the currents of northern public opinion, and able to get along with all elements of his party, Johnson was stubborn, deeply racist, and insensitive to the opinions of others. If anyone was responsible for the wreck of his presidency, it was Johnson himself."
