The correct statement about the candidates in the Election of 1860 is:
None of the candidates had widespread support outside of one or two regions of the country.
In the 1860 election, Abraham Lincoln was primarily supported in the Northern states, while other candidates like Stephen A. Douglas had support in the Midwest and parts of the North, John C. Breckinridge was backed in the Southern states, and John Bell appealed to some border states. This regional division highlighted the sectional tensions in the country at the time.
