CHARLES SUMNER
He was very critical of Arraham Lincoln even though he was a Republican. Many percieved that Lincoln's administration could not get anything done. Lincoln might have lost the 1864 campaign but for the great victory that General Sherman's troops had in taking Atlanta. This changed a lot of mionds about Lincoln's War strategy. Actually, in the first 2 years of the Civil War, Lincoln could not get his generals to fight his preferred kind of war until he appointed Grant who brought Sherman to high command.
Most of the factual accusations against Johnson were accurate. To this day it is argued whether the actions were impeachable offences or within the prerogatives and powers of the Presidency,
Charles Sumner was an American statesman and United States Senator from Massachusetts. As an academic lawyer and a powerful orator, Sumner was the leader of the anti-slavery forces in the state and a leader of the Radical Republicans in the U.S. Senate during the American Civil War. During Reconstruction, he fought to minimize the power of the ex-Confederates and guarantee equal rights to the freedmen. He fell into a dispute with President Ulysses Grant, a fellow Republican, over the control of Santo Domingo leading to the stripping of his power in the Senate and his subsequent effort to defeat Grant's re-election.
