well Georgia was a relatively democrat state until the 1990s. It was then that people from out of state started moving to places like Gwinnett or Forsyth to get away from the scary swarthy looking people from their home states.
You can't really say that Georgia was a Democratic state until the 1990s. That was certainly true at the state level, as was in the case in nearly every other southern state. On the national level we became a Republican state in the 60s and 70s, well before most of our growth happened.
And most people who have moved to Forsyth and other suburban counties are actually white people from inner city areas, like Atlanta and Dekalb County, so it's more of a shift than in influx. Although a lot of the out of state transplants kind of like to think of themselves as "blue state refugees."
But the largest migration to Georgia today comes from immigrants and minorities, who are more likely to vote Democrat, which is why I believe GA will trend left in the next decade.
