Quote from Mercor:
Yes, and the cycle continues.
Starting about year 1900 the Blacks leave the Democratic racist Jim Crow south. They head to the mostly Republican North and in the next 90 years old they vote Democratics in office until the Blacks become uneducated and segregated, stuck in projects, used for votes. Now they head back to the free and growing Republican south.
If they continue to vote for Democratics I am sure at some point ,again, they will need to leave another decaying situation and find the booming Republican territory.
