Nathaniel P. Banks had served as governor of Massachusetts since 1858. The state's Republican Party had re-nominated him but in a letter he declined a run for a second term. He was replaced on the ticket by John A. Andrew who was duly elected and became an energetic "war governor." Banks worked briefly for the Illinois Central Railroad before 1861, when he became one of Lincoln's first major-generals of volunteers. (By John Osborne)
