By the mid-nineteenth century, single-sheet broadside cartoons played an important role in electioneering. Some of these broadsheets were printed in quantities from 50,000 to 100,000 and distributed to party headquarters or sold from newspaper offices. The venerable Currier & Ives Lithography Company, the most prolific print publishers of the period, issued numerous cartoons in the election of 1860, satirizing all factions. Progressive Democracy features the dilemma of a divided Democratic Party. With Stephen Douglas and running mate Hershel V. Johnson pulling the "platform" one way while southerners John C. Breckinridge and Joseph Lane, driven by James Buchanan, strain in the other direction, Republican candidates Abraham Lincoln and Hannibal Hamlin anticipate the "smash up" of the Democratic Party.
