Bulloch County voted in line with most other Solid South counties prior to 1964, backing Democratic candidates for president by wide margins. The Civil Rights Act led to vast changes in political party makeup, & the county has not backed a Democratic candidate for president since Georgian Jimmy Carter was on the ballot in 1976 & 1980. However, the Republican margins of victory are not as high as other rural counties in the state as it has a sizable African-American minority and a large university in Georgia Southern University.
