Tréguer, Pascal (19. 2. 2018). „Original Meaning of 'bulldozer': A Racist Bully”. Word Histories. Приступљено 13. 3. 2022. „The noun bulldozer is first recorded in 1876, in the plural, in the sense of Southern members or supporters of the Democratic Party who colluded to disenfranchise African-American voters; after the American Civil War (1861-65), the 15th Amendment to the Constitution, ratified on 3rd February 1870, granted Afro-American men the right to vote ... The bulldozers, also known as regulators, used threats and acts of violence in order to prevent Afro-American voters from casting their ballots for candidates of the Republican Party.”CS1 одржавање: Формат датума (веза)
