Which of the following was probably least important in Lincoln being a successful president

Abraham Lincoln, a self-taught lawyer, legislator and vocal opponent of slavery, was elected 16th president of the United States in November 1860, shortly before the outbreak of the Civil War. Lincoln proved to be a shrewd military strategist and a savvy leader: His Emancipation Proclamation paved the way for slavery’s abolition, while his Gettysburg Address stands as one of the most famous pieces of oratory in American history. In April 1865, with the Union on the brink of victory, Abraham Lincoln was assassinated by Confederate sympathizer John Wilkes Booth. Lincoln’s assassination made him a martyr to the cause of liberty, and he is widely regarded as one of the greatest presidents in U.S. history. Lincoln was born on February 12, 1809 to Nancy and Thomas Lincoln in a one-room log cabin in Hardin County, Kentucky. His family moved to southern Indiana in 1816. Lincoln’s formal schooling was limited to three brief periods in local schools, as he had to work constantly to support his family.
