The election of 1856 saw Select one: a. no significant third party in the field. b. the Whig Party make a strong comeback. c. the Democrats elect a young and forceful pro-slavery leader. d. former president Millard Fillmore in the running. e. the Republicans run against the idea of internal improvements.

The correct answer is D. The election of 1856 saw former president Millard Fillmore in the running.

Explanation:

The presidential election in 1856 was the 18th presidential election in the history of the United States, and was an election in which the campaign was unusually hot. Republican candidate John Fremont condemned the Kansas-Nebraska Act and fought hard against slavery. Democrat James Buchanan warned against Republican extremism and believed that a Republican victory would lead to a civil war. Former President Millard Fillmore represented a third party, the relatively new Know-Nothing Party, which, instead of talking about slavery, focused on anti-immigration in the election campaign, giving them almost a quarter of the vote in the election.

The incumbent President, Franklin Pierce, had to fight himself to be renamed by the Democrats, who instead elected James Buchanan from Pennsylvania. This was partly due to the split in Kansas-Nebraska Act in the Democratic Party. The Whig Party had disbanded the slavery issue, and new groups, such as the Republican Party and the Know-Nothing Party, were competing to replace them.

Buchanan won the election with his Vice Presidential candidate John C. Breckinridge. With about 45% of the vote, he took office as the 15th president of the United States.
