<P> In the last three presidential elections as of 2018, the Republican candidate has won Georgia by approximately 5 - 8 points over the Democratic nominee, at least once for each election being narrower than margins recorded in some states that have flipped within that timeframe, such as Michigan, Ohio and Wisconsin . Therefore it could potentially be regarded as a swing state in future elections should voter preferences only shift slightly . </P> <P> During the 1960s and 1970s, Georgia made significant changes in civil rights and governance . As in many other states, its legislature had not reapportioned congressional districts according to population from 1931 to after the 1960 census . Problems of malapportionment in the state legislature, where rural districts had outsize power in relation to urban districts, such as Atlanta's, were corrected after the US Supreme Court ruling in Wesberry v. Sanders (1964). The court ruled that congressional districts had to be reapportioned to have essentially equal populations . </P> <P> A related case, Reynolds v. Sims (1964), required state legislatures to end their use of geographical districts or counties in favor of "one man, one vote;" that is, districts based upon approximately equal populations, to be reviewed and changed as necessary after each census . These changes resulted in residents of Atlanta and other urban areas gaining political power in Georgia in proportion to their populations . From the mid-1960s, the voting electorate increased after African Americans' rights to vote were enforced under civil rights law . </P> <P> Economic growth through this period was dominated by Atlanta and its region . It was a bedrock of the emerging "New South". From the late 20th century, Atlanta attracted headquarters and relocated workers of national companies, becoming more diverse, liberal and cosmopolitan than many areas of the state . </P>
