Almost 4.7 million people live in those 10 counties, or around 45 percent of the state’s population.
Until very recently, the Atlanta area wasn’t a liberal bastion. There was a Democratic bloc that long controlled the government within the city limits of Atlanta and a Republican bloc that once dominated the suburbs“
