If you think President Obama has problems going into the midterm election, consider what Abraham Lincoln faced. In fall 1862, the nation was 18 months into Civil War. Eleven states had left the Union and four slave states still within -- Delaware, Maryland, Kentucky and Missouri -- continued to cause Lincoln political problems. The elections were held at different times, with voters in Pennsylvania, Ohio and Indiana going to the polls in October, and Illinois, Missouri, Massachusetts, New York and New Jersey in November.
