The October surprise of the election was the endorsement of the Democrat Douglas by former Whig John J. Crittenden. Non-Republican former Whigs comprised the biggest block of swing voters, and Crittenden's endorsement of Douglas rather than Lincoln, also a former Whig, reduced Lincoln's chances of winning. On election day, as the districts were drawn to favor Douglas' party, the Democrats won 40 seats in the state house of Representatives, and the Republicans won 35. In the state senate, Republicans held 11 seats, and Democrats held 14. Stephen A. Douglas was reelected by the legislature, 54–46, even though Lincoln's Republicans won the popular vote with a percentage of 50.6%, or by 3,402 votes. However, the widespread media coverage of the debates greatly raised Lincoln's national profile, making him a viable candidate for nomination as the Republican candidate in the upcoming 1860 presidential election. He would go on to secure both the nomination and the presidency, beating Douglas, among others, in the process. Lincoln also went on to be in contact with editors looking to publish the debate texts. George Parsons, the Ohio Republican committee chairman, got Lincoln in touch with Ohio's main political publisher, Follett and Foster, of Columbus. They published copies of the text, and titled the book, Political Debates Between Hon. Abraham Lincoln and Hon. Stephen A. Douglas in the Celebrated Campaign of 1858, in Illinois. Four printings were made, and the fourth sold 16,000 copies.
