According to this story in the Atlantic, the migration of African Americans from the Northeast to Georgia in particular (and the Southeast generally) may be a factor in the November 6 election. The reason it is called reverse migration? In the 20th century more than 10% of the Black population of the South left the oppressive, openly racist and anti-democracy regimes in Southern US states ( like Georgia) to mildly better regimes in the U.S. north. Emerging political representation, flourishing Black communities, and lower costs of living have been beckoning the descendants of the refugees of the 1920s and 50s back.
I ran some numbers on this a few months ago. It could very likely impact the Georgia governor election in which Stacey Abrams is in a statistical draw with the current Georgia Secretary of State (who seems to have nostalgic fondness for un-democratic practices of the 20th century). It will be interesting to see how the reverse migration factors in coming political social events.
