the Democratic primaries were further defined by their usage of the white primary to exclude African Americans and other ethnicities from participation, as well as the usage of the county unit system from 1898 to 1963 to allocate votes to winners along rural-biased lines. Historically, elections at all levels of government in the U.S. state of Georgia were dominated by conservative white Democrats in the period between Reconstruction and the end of the New Deal Coalition.
