Buchanan 's service abroad conveniently placed him outside of the country while the debate over the Kansas – Nebraska Act roiled the nation . While he did not overtly seek the presidency , he deliberately chose not to discourage the movement on his behalf , something that was well within his power on many occasions . The 1856 Democratic National Convention met in June 1856 , writing a platform that largely reflected Buchanan 's views , including support for the Fugitive Slave Law , an end to anti-slavery agitation , and U.S. " ascendancy in the Gulf of Mexico . " President Pierce hoped for re-nomination , while Senator Stephen A. Douglas also loomed as a strong candidate . Buchanan led on the first ballot , boosted by the support of powerful Senators John Slidell , Jesse Bright , and Thomas F. Bayard , who presented Buchanan as an experienced leader who could appeal to the North and South . Buchanan won the nomination after seventeen ballots , and was joined on the ticket by John C. Breckinridge of Kentucky
