[145] Fillmore's name has become a byword in popular culture for easily forgotten and inconsequential presidents.[146] Anna Prior, writing in The Wall Street Journal in 2010, said that Fillmore's very name connotes mediocrity.[147] Another Fillmore biographer, Finkelman, commented, "on the central issues of the age his vision was myopic and his legacy is worse ... in the end, Fillmore was always on the wrong side of the great moral and political issues."[148] Rayback, however, applauded "the warmth and wisdom with which he had defended the Union".[149] Smith, on the other hand, found Fillmore "a conscientious president" who honored his oath of office by enforcing the Fugitive Slave Act rather than govern based on his personal preferences.[150] Steven G. Calabresi and Christopher S. Yoo, in their study of presidential power, deemed Fillmore "a faithful executor of the laws of the United States – for good and for ill".[151] However, according to Smith, the enforcement of the Act has given Fillmore an undeserved pro-southern reputation.
