Prior to the vote to remove the capital city from Omaha, a last ditch effort by Omaha Senator J. N. H. Patrick attempted to derail the move by having the future capital city named after recently assassinated President Abraham Lincoln. Many of the people south of the Platte River had been sympathetic to the Confederate cause in the recently concluded Civil War. It was assumed that senators south of the river would not vote to pass the measure if the future capital was named after the former president.
