I think what you meant to say was, that demographics of typically non-voting, but potentially Democrat voters, were activated in 2020, to flip GA.

No Republicans flipped to make GA go blue. It was massive turn out from black and youth voters.

The idea that Republicans do 'flip' or will ever 'flip' is a damaging fiction.
