Who is the best president in the US

Lincoln: He also encouraged border states to outlaw slavery, and promoted the Thirteenth Amendment to the United States Constitution, which outlawed slavery across the country.

Lincoln managed his own successful re-election campaign. He sought to heal the war-torn nation through reconciliation. On April 14, 1865, just days after the war's end at Appomattox, Lincoln was attending a play at Ford's Theatre with his wife Mary when he was assassinated by Confederate sympathizer John Wilkes Booth.
