bulldoze (v.) Look up bulldoze at Dictionary.com
by 1880, "intimidate by violence," from an earlier noun, bulldose "a severe beating or lashing" (1876), said by contemporary sources to be literally "a dose fit for a bull," a slang word referring to the intimidation beating of black voters (by either blacks or whites) in the chaotic 1876 U.S. presidential election. See bull (n.1) + dose (n.). The bull element in it seems to be connected to that in bull-whip and might be directly from that word. Meaning "use a mechanical ground-clearing caterpillar tractor" is from 1942 (see bulldozer); figurative use in this sense is by 1948. Related: Bulldozed; bulldozing.
