 Brown County is part of the German-settled area of western Central Illinois and the Missouri Rhineland centred on the St. Louis metropolitan area.This region was opposed both to southern plantation owners and socially liberal Yankees and consequently voted against the majority of people in their state.Brown County voted for the Democratic candidate in every presidential election from at least 1840 through 1948, with the sole exception of the 1928 election when the county voted for the Republican candidate Herbert Hoover.
