38. William Henry Harrison (1841)
Harrison received the lowest rankings for his crisis leadership skills, but since Harrison died on his 32nd day in office, historians have little to judge him. However, historian William W. Freehling calls him “the most dominant figure in the Northwest territories’ evolution into the Upper Midwest today.”
37. Millard Fillmore (1850-1853)
Historians have blamed Fillmore for signing the Fugitive Slave Act, which required the return of escaped slaves to their masters. Of course, in 1852, he failed to win the Whig presidential nomination. Still, four years later, he gained the nativist Know-Nothing Party’s endorsement and finished third in the presidential election of 1856.
