What are some similarities and differences between presidential reconstruction and radical reconstruction

Abraham Lincoln's plan of Reconstruction was conceived to reunite a divided country with a healing hand. His motives can best be summarized by the words from his second inaugural address, which advocated that the United States heal itself "with malice towards none, with charity for all." This plan was centered on the ten percent rule. This magnanimous provision stated that the former Confederate states would be welcomed back into the Union once ten percent of their voters publicly swore their loyalty to the country.
